The tensile strength of wheel spacers refers to the amount of load or stress that a spacer can handle before it stretches and breaks. As the name states, tensile strength is the resistance to the tension that is caused by mechanical forces applied to the wheel spacers.
Imagine that you hold a rope, when applying opposite forces at both ends with your hands, you feel that there is a force that tries to straighten the rope. That force is the tension. And the ability of the rope to withstand this pulling (tensile) force is called tensile strength. As the force becomes greater and greater, the rope breaks when this tensile force crosses a certain threshold. The force which causes the rope breaks is called the ultimate tensile strength (load).
Are Wheel Spacers with Higher Tensile Strength Better?
The tensile strength is an important property of wheel spacers to determine their mechanical performance. It is the ability of a spacer to resist tearing due to tension. The higher the tensile strength, the more tensile stress that the wheel spacers can withstand before failure. When tensile strength is effectively increased, total toughness is growth. High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking. Therefore, yes, wheel spacers with higher tensile strength are safer and better.
Although higher tensile strength is better, the actual definition of failure usually varies according to the material’s type and design. Since forging produces a uniform grain structure, it increases the strength of wheel spacers. After continuous tons of pressure, the forging process eliminates internal voids/gas pockets that weaken metal parts, maximizing fatigue resistance and increasing impact strength. In summary, the forging process increases about 30% in strength/toughness over the original billet it was made from.
What Are Yield Strength of Wheel Spacers?
The yield strength of wheel spacers is similar to ultimate tensile strength. But they are actually different. Yield strength is defined as the maximum stress that a wheel spacer can withstand when it is deformed within its elastic limit. Ultimate tensile strength is the maximum stress or load that a spacer can sustain before complete fracture under external load. Most engineering material tests show that ultimate strength is 1.5 – 2.0 times higher than yield strength.
If the external stress is higher than the yield strength, wheel spacers deformation occurs. So, wheel spacers with higher yield strength behave more resistive under deformation and thus can retain their shapes and sizes intact under comparatively higher loading. Like the tensile strength, the yield strength of a material can be increased by certain forging processes. When selecting wheel spacers, it is always a good idea to review these two critical mechanical properties.
