Non-ferrous metal

Properties of screws and nuts made from aluminium alloys

Non-binding information depending on manufacturer

The values in the table are for: density = 2,8 kg/dm3, coefficient of thermal expansion = 23,6 · 10–6 · K–1, modulus of elasticity = 70 000 N/mm2

non ferrous metal properties of screws and nuts made form aluminium alloys

1) Subject to stress corrosion cracking due to the high copper content
2) Elongation at break A – Test on bolt with 2 x d grip length
3) T6 – Solution heat-treated and artificially aged
   T8 – Solution heat-treated, cold-formed, and artificially aged
   T 73 – Solution heat-treated and artificially overaged (artificially aged) in order to achieve the best stress corrosion resistance

Properties of screws and nuts made from copper alloys

Non-binding information depending on manufacturer

non ferrous metal properties of screws and nuts made from copper alloys

1) Cold strain hardening
2) Elongation at break A5 – Test on machined test rod with 5 x d test length
3) 1 N/mm2 = 1 MPa
Minimum breaking torque for screws up to M5

according to ISO 8839

non ferrous metal minimum breaking torque for screws up tp M5

1) The torque test is to be carried out in according to ISO 898-7
