Material: super steel wire, stainless steel, copper, brass, aluminum application: Standard rivets are made from red copper, brass, silver alloy, iron wire and special-grade steel wire through forging, hardening and tempering. Provides optimum riveting performance in a very wide range of applications. It can be produced into ordinary rivets, special-shaped rivets, hollow rivets, hollow rivets, etc. Austenitic stainless steel rivets - for riveting stainless steel sheets with lower hardness; - Copper rivets - used for riveting special plates, such as copper and brass wires; - Martensitic stainless steel rivets - for riveting high hardness stainless steel plates that cannot be joined by austenitic stainless steel rivets. - Aluminium rivets - for riveting lower hardness aluminium sheets. advantage: Iron, low cost, high tensile force, high cost of aluminum and copper, good corrosion resistance Capacity: 30 million capsules/month
