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|

|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 .
|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.|
Blind rivets are generally used to various fields like aerospace ,airplane ,vehicle and building ,electric appliances ,furniture etc .
