Property data for aluminium alloys included in updated MPIF Standard 35

December 7, 2017

The MPIF issued a new update on MPIF Standard 35 in October 2017, which now includes mechanical property data, elongation and hardness values on two aluminium alloys – AC-2014-32-T8 and AC-2014-38-T8 – produced by Powder Metallurgy. The updated standard gives a Rockwell hardness of 75 for AC-2014-32-T8 and 83 for the AC-2014-38-T8.

The T in both PM grade aluminium alloys refers to the heat treatment which the alloys undergo. Because of their relative high strength in a range of temperatures, and their overall mechanical properties, these Al alloys are often used in aerospace applications.

The MPIF Standard 35 family of publications comprises four separate publications dealing with materials for conventional PM structural parts, PM self-lubricating bearings, powder forged (PF) steel and Metal Injection Moulded (MIM) parts.

The same materials may appear in more than one publication or section of the standard depending upon their common use, e.g., some structural materials may also be used in bearing applications and vice versa, and stainless steel materials may be manufactured by more than one PM process, such as conventional PM or MIM, dependent on part design and use.
