Aluminium allowable surface pressure

Aluminium allowable surface pressure

Aluminium allowable surface pressure

(OP)
Could someone give me datas on allowable surface pressure of aluminium under pressure of a tightened screw
The material is die-cast aluminium ref :
Al-Si8 Cu3Fe according ISO3522
A380.0 / SC84A according to ASTM B85

RE: Aluminium allowable surface pressure

This type of data is not published widely.  The closest I have seen is this:

G AlSi9Cu3, Werkstoffnummer 3.2163.01, Rm = 304 MPa, Rp0,2 = 168 MPa, A5 = 4.5%, HB = 103, pG = 383 MPa

GD AlSi9Cu3, Werkatoffnummer 3.2163.05, Rm = 232 MPa, Rp0,2 = 159 MPa, A5 = 2%, HB = 88, pG = 367 MPa

Cory
