Aluminum 1070 vs 1080

Aluminum · grade comparison

Aluminum 1070 and 1080 are both aluminum grades, both electrical conductive al. Both yield at about 25 MPa — strength does not separate them. 1080 is harder — 20 HB against 19 HB for 1070 — which matters for wear surfaces and threads.

1070 vs 1080 — frequently asked

What is the difference between 1070 and 1080?

Aluminum 1070 and 1080 are both aluminum grades, both electrical conductive al. Both yield at about 25 MPa — strength does not separate them. 1080 is harder — 20 HB against 19 HB for 1070 — which matters for wear surfaces and threads.

Which is cheaper, 1070 or 1080?

Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 1070 or 1080?

1070. Its machinability rates fair (35/100) against poor (30/100) for 1080.
