Abstract

The invention discloses a soldering tin material used for automotive glass hot-coating belts and application of the soldering tin material. The soldering tin material is impact-resistant, temperature-resistant, proper in tensile-shear strength, low in welding temperature and melting point, capable of greatly reducing stress change among alloy materials and effectively preventing fatigue ageing and shedding of metals, excellent in performance and stable in quality, has all aspects to reach or exceed requirements of international similar products and is capable of providing high-quality service for automotive glass factories. The soldering tin material comprises tin, lead, silver and bismuth and is characterized by comprising, by weight, 20-30% of the tin, 58-68% of the lead, 4-14% of the bismuth and 0.3-5% of the silver.

Description
