Amaero International Limited, a world-class additive manufacturing specialist, announced that it has applied for broad international patent coverage for its high-performance aluminium alloy Amaero HOT AI. The new heat treatable alloy has already entered the final approval stage, the national phase of the Patent Co-operation Treaty (“PCT”), with three out of four stages of patent application already completed.

Amaero HOT AI is a new high-performance aluminium alloy with scandium and manganese alloying, resulting in 3D printed parts that can be directly treated with age-hardening heat treatment to yield superior strength and durability at high operating temperature.

“There has been a significant amount of work completed over more than half a century to improve the heat tolerance of aluminium alloys, to allow them to withstand higher operating temperatures without degradation of mechanical properties. Today, we have a solution through the Company’s newly developed Aluminium-scandium alloy, Amaero HOT Al,” said Barrie Finnin, Amaero CEO.

Aluminium-scandium alloys are widely used in the aerospace and sports equipment industries, such as for the manufacture of tennis rackets, baseball bats, bicycle frames, and multiple other applications that primarily rely on high-performance materials.

Amaero’s foremost strategy for global patent application is to be able to expand its alloy offerings through the commercialisation of metal alloys developed by research partners. This is the second patented alloy that Amaero holds exclusive global commercial license rights to.

The PCT is an international treaty having contracts with more than 150 countries. It allows patent protection in a large number of countries by a single filling for international patent application.
