      • Tin-based bearing alloy arc welding - Babbitt wire

    Our research and development of tin- based bearing alloy wire ( babbitt wire ) using tin (Sn) as the matrix material . Antimony (Sb) and copper (Cu) alloy particle hardening element , coupled with grain refiner made arc welding. The product has a uniform alloy composition, excellent seizure resistance , lubricity and load carrying oil storage and other features . For large marine diesel engines , bearing manufacturing turbines, alternators, mining equipment and large rotating machinery.

    ☆ applies to TIG welding - TIG or MIG welding - welding MIG welding process, the process of the current international tin- based bearing wear and create new process method .

    ☆ This product can be used directly in the steel substrate surface directly arc welding forming, welding alloy composition of the alloy layer is correct, fine crystalline , uniform particle distribution , and base metal welded steel base is good , improved load bearing, oil storage, lubricating performance and service life . The tin based Babbitt alloy arc welding process is a new technology in the world and the elimination of the original casting methods.

    ☆ alloy organizational characteristics : soft phase in the Sn matrix dispersed hard particles , embedded with the alloy has a very good resistance, compliance and seizure resistance ; soft matrix concave , convex hard particles , good lubrication oil storage , which will help reduce wear and tear.

    ☆ product packaging 5Kg, 10Kg, 15Kg, 20Kg, 25Kg / plastic plate, diameter ф1.6 ~ ф4.0mm for you to choose .
    Product performance standards : GB / T 8740 - 1988 bearing alloy casting
