Xtalic’s new nickel-gold alloy is ideal for fine pitch interconnects that require superior strength, durability, and conductivity while being exposed to high temperatures. Features of Xtalic’s nickel-gold alloy include strength up to 2,000 MPa, resistivity down to 12 µΩ-cm, and more than 1,000 MPa fatigue life at temperatures up to 400oC.

“Xtalic nickel-gold alloy uses a small amount of gold to control the nickel grain size, create a thermodynamically stable super-saturated solid solution, and find the optimal balance of electrical and mechanical properties,” said Tom Clay, Xtalic’s chief executive officer. “Our nickel-gold alloy fulfills the need for high-current-carrying miniaturized electrical contacts in applications throughout the consumer electronic, automotive, and semiconductor industries.”

Moreover, Xtalic will work with designers to tailor nickel-gold properties to meet specific challenges across a variety of other applications — by leveraging its Dynamic Nanostructure Control® and patented Rapid Alloy Design toolkits.
