• Perfect for surfacing applications in corrosive environments

Silicon bronze welding rods are particularly valued in automotive restoration for their ability to weld body panels without warping, their attractive bronze finish, and their excellent flow characteristics. The lower melting point compared to steel makes these rods ideal for thin sheet metal work where heat distortion is a concern. This filler metal produces strong, ductile welds with excellent resistance to saltwater and atmospheric corrosion, making it suitable for marine applications as well.
