Summary:
Tyre bead wire is made of high carbon steel wire rods and coated by bronze or brass (red copper accepted but not recommended) widely used as enhanced framework material for reinforcement in tyre production.
Brief Introduction:
Tyre bead wire is sort of high carbon steel wire with carbon content approximately 0.60%-0.90% in percentage. Tyre bead wire is coated by bronze or brass conventionally and so that it has the typical property of good adhesive force with rubber and higher strength of elasticity, as well as its qualified anti-fatigue performance, straightness feature and high tensile strength. Further, during wire drawing process, tyre bead wire’s compression ratio dies to dies should be at 20% approximately in percentage and general compression ratio at 80% in percentage. In order to get perfect linearity, tempering treatment and the straightener dealing are both required for tyre bead wire. In addtion that, as the lightweight design and trend of automobile development, the demands to tyre bead wire’s comprehensive perfermance come to a higher level, and wire torsion property is necessarily in quality judgement since it has been closely connected with wire service life.
Tyre bead wire obviously can reduce tyre weight of its own and accordingly its ground rolling resistance, which directly lead to lower fuel consumption that definitely conformed to country sustainable development policy of tyre industry. As the reinforced framework material, tyre bead wire can effectively prevent tyre from being out of shape due to abnormal air pressure or external forces. Meanwhile, tyre bead wire can keep the tyre away from irregular vibration by maximum during driving for safety. For those advantages, tyre bead wire is broadly required and used in automobile vehicle tyres, plane tyres, heavy equipment tyres and other rubber products. Generally in words, tyre bead wire enjoys perfect practicability, effectiveness, economical costs and safety.
Tyre bead wire specification is list as below. However, tyre bead wire manufacturing process is certain different company to company so that customer’s detailed requirement or confirmed manufacturing standard should be necessary before order.
