Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and electricity. [ 2 ]

An average 70 kg human body is about 0.01% heavy metals (~7 g, equivalent to the weight of two dried peas, with iron at 4 g, zinc at 2.5 g, and lead at 0.12 g comprising the three main constituents), 2% light metals (~1.4 kg, the weight of a bottle of wine) and nearly 98% nonmetals (mostly water).
A Rockwell hardness tester. The Rockwell hardness test is a hardness test based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]

Traditionally, the wear of materials has been characterized by weight loss and wear rate. However, studies have found that wear coefficient is more suitable. The reason being that it takes the wear rate, the applied load, and the hardness of the wear pin into account. Although, measurement variations by an order of 10-1 have been observed, the ...
Materion Corp. is a multinational company specializing in high-performance engineered materials.Among their products are precious and non-precious metals, inorganic chemicals, specialty coatings, beryllium, specialty engineered beryllium, beryllium copper alloys, ceramics, and engineered clad and plated metal systems.
Glucydur is a beryllium bronze; an alloy of beryllium, copper and iron. In addition to its low coefficient of thermal expansion, its hardness (400 Brinell ), nonmagnetizability, and resistance to deformation and damage make it suited for making precision parts that must have high dimensional stability.
