Bead Wire

Short Description:

The material:   82B, 77B

The wire diameter(mm):   0.89~1.65

The Tensile Strength(mpa):  1750~2350

The package: packed in reels,then put on the pallets / Net weight of wire is of 400kg +-5%

The Application: The bead wire can reduce the weight of tire/tyre,reducing the rolling resistance,saving energy, and reduce the production cost of the tire.But it can prolong the service life of tires.
