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 ...

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 ...

Metal and metallic alloy casting is widely used for manufacturing components in high-performance industries, including automotive and aerospace. However, cast metallic alloys often exhibit limitations ...

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 ...

Dr Mike McDonagh provides insight into the factors involved in choosing and processing suitable alternative antimony alloys for lead-acid battery ...

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 ...

Different methods are employed to vary cooling rates for magnesium alloys during the solidification process from liquid to solid phase and after the solution/aging heat treatment. These include using ...
