About AerMet® 100

AerMet® 100 provides high hardness and ultra-high strength combined with exceptional ductility and fracture toughness. The alloy has a minimum tensile strength of 1930 MPa (280 ksi) and a minimum fracture toughness of 100 ksi.

The exceptional combination of hardness, toughness, tensile strength and ductility  makes this alloy a candidate for aerospace applications including landing gear, engine shafts and drive shafts.

AerMet® 100 may be considered for use up to about 427°C.

FAQs & Resources

Although there are many acceptable ways to measure hardness of a material, the most commonly used method in metallurgy is to measure the size of an indentation made by a hardness testing machine. The measurement varies with the weight and scale used during the testing which, in turn, depend on the type of the material being tested. The most commonly used scales are Rockwell A/B/C, Brinell, Vickers and Knoop.

Tensile strength is the amount of tension or tensile force required to stretch the material until it starts necking and eventually breaks apart. It is also referred to as the Ultimate Tensile Strength (UTS). Tensile strength or the UTS are one of the most common physical properties measured and used across the metal industry. To find out more about specific tensile strength or the UTS of NeoNickel alloys, please see our downloadable data sheet on our alloy pages!

AMS materials tend to be used in the production of parts and components in the aviation and motorsport industry where the integrity of the materials is critical. AMS stands for Aerospace Material Specification in the metal industry. Aerospace Material Specification cover a wide range of alloy grades ranging from stainless steel to titanium and nickel alloys.
