Lead-free solder alloys have been around for as long as people have done soldering, with sources dating back about 5,000 years. Most of these alloys were combinations like copper-silver or silver-gold ...

Electrical conductivity: copper has the highest conductivity of the engineering metals. Silver or other elements may be added to increase strength, softening resistance or other properties without ...

Aluminium alloy 2011 has extremely poor weldability and thus welding is not recommended. However, as it is used for machined parts there is rarely a need to weld this alloy. This Data is indicative ...

With a view to constructing more durable components that can withstand the very harsh environments in and around aircraft and jet engines, NASA researchers have developed a novel metal alloy with an ...

Scientists have successfully developed a super-strong, highly ductile and super-light titanium-based alloy using additive manufacturing, commonly known as 3D printing. Their findings open up a new ...

High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic ...

Ingenious people have produced alloys since ancient times. By trial and error, they mixed metals and other elements until the whole came out better than any component alone. In recent years, some ...

The North American Die Casting Association (NADCA) developed i-Select Al software to help designers, product specifiers, and die casters identify aluminum alloys that have specific casting properties.

Engineers have spent decades trying to build metals that do not snap, melt, or grind away under extreme conditions, and for a ...
