Fastener Material Key
|
A1 Stainless Steel - Also known as grade 303. A general purpose grade of stainless steel but with better fabrication/machining properties than grade 304. |
|
A2 Stainless Steel - Also known as grade 304 or 18/8. A general purpose grade of stainless steel. |
|
A4 Stainless Steel - Also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel. |
|
Black Coated Aluminium - Black coated lightweight aluminium, with a steel mandrel. |
|
Plain Aluminium - Typically for blind rivets, plain, unpainted lightweight aluminium, with a steel mandrel. |
|
White Coated Aluminium - White coated lightweight aluminium, with a steel mandrel. |
|
Copper Alloy - Copper has good corrosion resistance and high tensile strength, allowing it to withstand high-pressure and high temperature conditions. It is a highly ductile and malleable material, enabling copper washers to create tighter seals and withstand vibration better than steel. Copper also provides excellent thermal and electrical conductivity. |
|
Stainless Steel (1.4122) - A martensitic grade of stainless steel, offering increased hardness and wear resistance over the more common austenitic grades 304 and 316. |
|
301 Stainless Steel - More elastic stainless steel grade used for springs and parts that require some higher strength. |
