Titanium 2023 BMW M2C wheel bolts are designed for customers seeking track performance and ultimate lightweight. The forged titanium 2023 BMW M2C wheel bolts are the best choice if you want lighter, unsprung weight and higher acceleration efficiency. Titanium has many benefits over traditional steel alloy wheel bolts, including weight, rust resistance, temperature effects, and specific strength.
Carbon steel 2023 BMW M2C wheel bolts have always been considered reliable. Generally, the higher the carbon content in carbon steel, the harder it is and the higher the strength, but the lower plasticity. Hardness and toughness are hardly compatible. Titanium alloys are only 60% as dense as steel alloys, which makes titanium 2023 BMW M2C wheel bolts lighter, and some high-strength titanium alloys exceed the strength of many alloys’ structural steels. Therefore, titanium alloys’ specific strength (strength/density) is much greater than other metal structural materials, which can produce parts with high unit strength, good rigidity, and lightweight.
Why Are Titanium 2023 BMW M2C Wheel Bolts Better than Steel?
Steel alloy 2023 BMW M2C wheel bolts are safe. We discuss whether titanium alloy 2023 BMW M2C wheel bolts are worth buying for track or performance-seeking customers because both can be used safely. Wheel bolts are generally made of the following materials:
- Cast iron casting 2023 BMW M2C wheel bolts the material is cast iron. Most of the stock car wheel bolts are this, and for a long time, they will rust. The color is also relatively single, but the cost is low;
- Cast iron forged 2023 BMW M2C wheel bolts, material cast iron, color made abundant than cast, forged tensile strength, and other properties have significantly improved.
- Aluminum forged 2023 BMW M2C wheel bolts, the material is generally 7075 aluminum, a small number of high-grade car stock wheel bolts with this process, a variety of colors, lighter weight than cast iron wheel bolts, strength is lower than iron.
- Titanium alloy 2023 BMW M2C wheel bolts; this type of wheel bolt is expensive, but the performance is much higher than the previous three. However, the previous three wheel bolts are also sufficient in terms of use. If you are looking for a lightweight and more special appearance, a set of titanium wheel bolts is also a good investment.
Temperature Effect
Titanium alloy 2023 BMW M2C wheel bolts can maintain the required strength at moderate heat resistance and work long at temperatures from 450°C to 500°C. Titanium alloy 2023 BMW M2C wheel bolts still have high specific strength from 150°C to 500°C. The performance of titanium alloy in terms of temperature is better than the general cast iron materials, not only in the high-temperature performance, titanium alloy 2023 BMW M2C wheel bolts in the low-temperature state still maintain their mechanical properties. Titanium alloys with good low-temperature performance and very low interstitial elements, such as TA7, can maintain a certain degree of plasticity at -253°C.
The reason for discussing the heat resistance of titanium alloy 2023 BMW M2C wheel bolts is that fasteners working close to the brake need to withstand higher temperatures. If the heat resistance of the fastener is not strong enough may lead to plastic deformation and missing clamping force. Thermal expansion and contraction rates are also considered in manufacturing titanium 2023 BMW M2C wheel bolts. Compared to typical cast iron wheel bolts, the titanium 2023 BMW M2C wheel bolt performs better in terms of temperature variation.
Rust Resistance
The rust resistance of Titanium 2023 BMW M2C wheel bolts is far superior to cast iron. Titanium 2023 BMW M2C wheel bolts can work in humid atmospheric and seawater media. Many customers who drive on the seaside or in the countryside all year round have complained of varying corrosion on their stock wheel bolts. However, the corrosion resistance of titanium alloy 2023 BMW M2C wheel bolts is far better than that of stainless steel; it is particularly resistant to pitting, acid corrosion, and stress corrosion; it has excellent resistance to alkali, chloride, organic substances of chlorine, nitric acid, sulfuric acid, etc.
Cast iron 2023 BMW M2C wheel bolts are mainly protected against rust by chromium plating or galvanizing. Still, chromium plating or galvanizing is not easy to avoid for high-strength wheel bolts of grade 10.9 and above, and the problem is hydrogen embrittlement.
Hydrogen embrittlement is the concentration of hydrogen dissolved in the steel, which causes stress concentration and exceeds the strength limit of the steel, forming small cracks inside the steel, also known as white spots. Once hydrogen embrittlement is generated, it cannot be eliminated. The internal residual or applied stress causes embrittlement or even cracking of the material.
Titanium alloy 2023 BMW M2C wheel bolts have an excellent titanium oxide rust protection layer on the surface. Combined with BONOSS’ hard anodized rust protection technology, the thickened titanium oxide layer effectively prevents rust from appearing on the inner metal.
Lightweight
Titanium 2023 BMW M2C wheel bolts are considered the spokesman for lightweight car parts. Not only wheel bolts but also various engine parts and the lightweight feature are often why many customers choose titanium 2023 BMW M2C wheel bolts. Titanium is used in various automotive applications and has significant weight advantages.
Car engine valves made of titanium alloy not only reduce mass and extend service life but also reduce fuel consumption and improve the reliability of the car. Compared with steel valves, the mass of titanium valves can be reduced by 30% to 40%, and the engine limit speed can be increased by 20%. Mitsubishi Motors uses Ti-22V-4Al titanium alloy valve spring seats in its mass production vehicles, compared with the original steel latch to reduce the mass by 42%, the valve train reduced by 6% of the inertial mass, the maximum engine speed increased by 300r/min. titanium alloy 2023 BMW M2C wheel bolts’ overall weight can also achieve a 20%-30% reduction.
Each Titanium 2023 BMW M2C wheel bolt weighs only 62g, and 20 pieces of titanium 2023 BMW M2C wheel bolts weigh 1240g. The 2023 BMW M2C is a performance car, and if you want to maximize the handling and power burst performance, the under-spring mass must also be light. Lighter forged aluminum wheels with forged titanium 2023 BMW M2C wheel bolts would be an effective upgrade solution. A 1kg reduction in under-spring mass is roughly equivalent to a 10kg reduction in upper-spring mass, and the lighter the under-spring weight, the easier it will be for the 2023 BMW M2C to stop the tires when braking (more effective braking).
Strength
The manufacturers of automotive wheel bolts generally refer to wheel bolts with strength 8.8 and above, made of low-carbon alloy steel or medium-carbon steel, and heat-treated as high-strength bolts. 2023 BMW M2C stock wheel bolts are high-strength, and the strength of the bolts varies with different models and load capacities, with 10.9 being the most common, 8.8 being generally matched to lower-end models, and 12.9 being generally matched to heavy-duty trucks. 8.8 is generally matched to the lower end of the car, and 12.9 is generally matched to the heavy-duty truck. The strength of titanium 2023 BMW M2C wheel bolts is stronger than the stock 10.9-grade wheel bolts.
2023 BMW M2C wheel bolts are generally made of high-strength steel, and the strength grade of the wheel bolts is printed on the head of the wheel bolts. There are several kinds, 8.8, 10.9, and 12.9. The higher the value, the higher the strength.
Here 8.8, 10.9, 12.9 refers to the bolt performance grade mark, consisting of two parts of the number, respectively, the nominal tensile strength value of the bolt material and the flexural strength ratio value, generally expressed in “X.Y,” such as 8.8, 10.9, 12.9 and so on. Performance grade 10.9 2023 BMW M2C stock wheel bolts have a tensile strength of 1000MPa and a yield strength ratio of 0.9, resulting in yield strength of 1000 x 0.9 = 900MPa, while titanium 2023 BMW M2C wheel bolts have a tensile strength of 1110MPa to meet the intense driving requirements of customers on track days.
How Much of Titanium 2023 BMW M2C Wheel Bolts?
The price of forged titanium 2023 BMW M2C wheel bolts is higher than the general grade-10.9-wheel bolts, which is the disadvantage of titanium 2023 BMW M2C wheel bolts due to the greater difficulty in processing titanium 2023 BMW M2C wheel bolts. The main limitation of forged titanium 2023 BMW M2C wheel bolts is the poor chemical reactivity with other materials at high temperatures.
This property forces titanium alloys to be different from the usual traditional refining, melting, and casting techniques and often even cause damage to the failure; as a result, forged titanium 2023 BMW M2C wheel bolts are very expensive. Whether the metal is initially smelted or subsequently machined, titanium alloys are far more expensive than other metals. The automotive industry can accept the cost of titanium parts, most of which are 6-15 times more expensive than aluminum plates and 45-83 times more expensive than steel plates.
BONOSS only offers forged titanium 2023 BMW M2C wheel bolts for performance cars like the 2023 BMW M2C. The total price for 20 pieces of forged titanium 2023 BMW M2C wheel bolts is US$599, and if you buy during the campaign, you can enjoy a 15% discount for US$509.
Washer Cushion Design
If you look closely at the bolts fitted to most BMW models, you will see that they are all in one design. Aftermarket wheel bolts are designed to be more versatile based on the safety of the stock bolts. This includes the washer design; the titanium 2023 BMW M2C wheel bolts use a washer designed to fit the wheel seat. The conical seat ensures maximum contact area to generate clamping force and static friction.
The one-piece design is safe, and titanium 2023 BMW M2C wheel bolts with washers are better. The washers are used as spacers to protect the wheel seat surface and the wheel bolt’s surface from wear and tear, distribute the wheel’s pressure on the 2023 BMW M2C wheel bolts and reduce disengagement from vibration. The washers on the titanium 2023 BMW M2C wheel bolts are made of 7075-T6 forged aluminum alloy. The hard anodized rustproofing allows them to continuously and effectively cushion road feedback, allowing the titanium 2023 BMW M2C wheel bolts to maintain a fixed clamping force for greater safety.
