Blind rivets generally manufactured in full aluminum material , besides , stainless steel , carbon steel and copper or brass can be used . and sometimes mixture of materials are taken eg , aluminum head with steel mandrel .
Stainless steel : SUS 201 , SUS303 , SUS 304 ,SUS 316 , SUS 416 ,SUS 430 and SUS 420 |
Carbon steel : 1008 , 1010 , 1018 , 1022 , 1035 , 1045 , SCM 435 and 40CRO |
Aluminum : 2024 , 6061 and 7075 |
Brass : CuZn35 , CuZn37 , CuZn40 , CuZn37Pb1 and CuZn39Pb1 |
Normally, aluminum blind rivets are not plated as itself with corrosion resistance , but other materials like steel should be plated .
Finish | Description |
Zinc | Various color can be choosed and perfect on anti-corrosion |
Nickel | Make the surface of the screws more bright and hardened and the performance of screws will be improved |
Polish | Improving the brightness of surface but is inferior is not as zinc in anti-corrosion |
Tin | Perfect to be anti-rust , and widely used to components |
Brass | It is usually used with Nickel for more good anti-corrrosion. |
Paint | Its powder paint with colors to prevent surface from rust. |
