Liquid phase sintered aluminum alloy for binder jet printing

A method to form an alloy for binder jet printing, the method comprising:

• mixing:
• aluminum;
• tin;
• and
• magnesium to form a mixture, wherein an amount of magnesium is between about 2.5% to 6.5% by weight of the mixture;
• selectively combining the mixture with a binder to form a shape;
• debinding the mixture;
• and
• liquid phase sintering the mixture with nitrogen.

An alloy for liquid phase sintering in binder jet printing, the alloy comprising:

• a mixture of:
• aluminum;
• tin;
• and
• magnesium,
• wherein an amount of the tin is about 1% by weight of the mixture and an amount of the magnesium is between about 2.5% to 6.5% by weight of the mixture, and wherein the remainder of the mixture is aluminum.
