Aluminium allowable surface pressure 1

[julio]

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

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

G AlSi9Cu3, Werkstoffnummer 3.2163.01, R[sub]m[/sub] = 304 MPa, R[sub]p0,2[/sub] = 168 MPa, A[sub]5[/sub] = 4.5%, HB = 103, p[sub]G[/sub] = 383 MPa

GD AlSi9Cu3, Werkatoffnummer 3.2163.05, R[sub]m[/sub] = 232 MPa, R[sub]p0,2[/sub] = 159 MPa, A[sub]5[/sub] = 2%, HB = 88, p[sub]G[/sub] = 367 MPa
