Description:

Bead wire for tire rim is widely applied to the manufacturing of various tires rims for automobiles, motorcycles, planes as well as other vehicles.It’s the pivotal material of tire, which can strengthen the tire and is considered an important raw material for the tyre manufacturing business.

Bead wire, its cross section is circular, wire attached to the surface of plating layer, the lap steel carbon content for the 0.80%-0.85%, when the bead wire diameter is 1.50mm, the diameter of the bead wire breaking force is greater than or equal to 3700N, the elongation in4%-7%, flexor strength ratio in 90% - 97% between. Using the improved lap steel strength and fatigue strength, the total strength of the same tire bead wire, can reduce the dosage, the weight of the tire is reduced, reduce the rolling resistance of tire, save energy, and reduce the tire production cost; has high flexion strength ratio, can reduce wire the creep, prolong the life of tires.
