ToughMet Copper-Nickel-Tin Alloys from Materion
ToughMet is Materion's family of high-strength copper-nickel-tin (Cu-Ni-Sn) alloys. They resist galling, wear under heavy load, and corrosion and stress-corrosion cracking in seawater, chlorides and sulfides; they are non-magnetic and free of lead and beryllium. VAN INTERTRADE supplies ToughMet 3 and ToughMet 2 in Thailand.
ToughMet gets its strength from spinodal heat treatment and has natural lubricity, which suits bushings and bearings in harsh service. Materion notes that in aircraft it can run safely for extended periods if lubrication fails, and in mining and construction it extends the life of parts exposed to silica, coal dust and salt.
