High-Conductivity Qmet Strip Alloy


From electric vehicles to consumer electronics, our QMet® alloy offers a unique combination of high conductivity, strength and formability to advance our customers' current and emerging technologies QMet alloy enables new designs that were previously unachievable.

QMet 300 alloy, a copper-chromium-silver material, has shown conductivity greater than all other alloys of similar strength, with sharp formability and stress relaxation resistance comparable to that of copper beryllium. For design engineers, the extra conductivity will allow them to create high current and high heat transfer components for smaller spaces than ever before.
