Bismuth, which is non-toxic and compliant with environmental regulations, is an important additive to copper and tin alloys. However, recent Chinese export controls have spiked prices and restricted bismuth supplies, forcing manufacturers to reevaluate sources and alloy formations. This article will explore the role of bismuth and identify potential substitutes. Bismuth’s Role in Copper and…

Bismuth is a unique specialty metal with a high density and low toxicity. It’s used in a broad range of applications, ranging from pharmaceuticals to atomic research. Manufacturers are increasingly turning to bismuth as a safer lead alternative in alloys, ammunition and food-processing equipment. Globally, bismuth is primarily produced as a byproduct of metal processing….

Shape memory alloys (SMAs) are a type of smart material that can temporarily alter their shape, reverting to their original form at certain temperatures. They have innovative applications in aerospace, automotives, robotics, and biomedicine. Nitinol, or nickel-titanium, has been used as an SMA since the 1960s. Copper-based shape memory alloys are emerging as a modern alternative due…

As the world relies less on fossil fuels, another natural resource is filling the void. Copper has many benefits — it’s durable, conductive, ductile, and recyclable. It’s a preferred solution in clean energy applications, including solar energy, wind turbines, and energy storage. By 2040, these types of renewable energy are expected to make up 61% of copper consumption….
