researchers have developed a copper alloy that is resilient.

The new alloy, a mixture of copper, tantalum and lithium.

Tantalum is has been used to make resistors for many decades.

Lithium is the stuff they make Li-ion batteries with.

The new copper alloy may cause the value of Silver to drop a bit.

But silver is not just an industrial metal. It is also a monetary metal and has been valued for 10,000 years as such.

Silver also has optical properties to make mirrors and sun shield visors.

Silver has a rare self-lubricating feature which makes it valuable in bearings.
