MW-4008 Aluminium Welding Wire
MW-4008 is produced with controlled lower levels of impurities than those present in alloys 4010 and 356.0, A356.0 and A357.0. MW-4008 aluminium welding wire meets the chemistry requirements of AMS 4181. The alloys 356.0, A356.0 and A357.0 are typically used to manufacture sand and permanent mould castings. Alloy 4008 is an excellent choice to join or repair these castings and, if needed, it can be heat treated in order to increase its mechanical properties.
