Tricalium MMC?

The Adal group has applied for a patent for a new Metal Matrix Composite, Ticalium.

"The new, engineered structure of Ticalium gives it excellent wear properties. The cutting and wear resistance of Ticalium can be increased by more than 50% at a significantly low reinforcement level.

The typical properties of Ticalium composite material from 6xxx Aluminium alloy is a hardness of 120 HV, a yield strength of 300 MPa, a tensile strength of 330 MPa and a stiffness of 85 GPa. These values are about 25% higher than those for the base alloy.

Dr Cem Selcuk, project manager for Adal, said in their September 19, 2005 news release, "Just for comparison with another strong material, white cast iron has a tensile strength of approximately 250 MPa (Mega Pascals)[sic] and is also brittle, whereas Ticalium has a higher strength of about 330 MPa together with a greater stiffness while exhibiting greater lightness according to third party testing."

It seems to possess a lot of interesting material properties, however there is very little information available.

Endurance limit?

Electrical Conductivity?

Thermal Conductivity?

Coefficient of Thermal Expansion? Electrical Resistance? Elasticity?
