Technical characteristics

CuBe2 alloy is known in Europe as alloy C17200 — popular grade of beryllium bronze. It contains 1,8−2% of beryllium. It gives strength, hardness, thermal resistance to a material. Limit of tensile strength of a C17200 sheet is more than 1380 MPa (200 KSI).This European alloy is used in all cases that require high strength, hardness, corrosion resistance and good conductivity.


Beryllium bronze sheet is one of the most requested semi-finished products due to high strength and excellent electro-technical properties. Beryllium bronze strip is a product with a rectangular cross section and length of 0.5 m. Beryllium sheet, strip, foil are characterized by high thermal resistance, high strength, forgeability, hardness. These properties make them suitable for die-molds. Beryllium plates have dense and homogeneous fine-grained microstructure. They have a minimal level of impurities and excellent workability. They are used in current-carrying blade safety clamps, spring connectors, details of electrical switches and navigation tools. They are also used for a manufacture of disk spring washer, relay cutting edges, fasteners, connectors, screws, washers. Bronze beryllium foil is used in instrument engineering and nuclear physics.

Industrial foil is manufactured by a method of hot rolling in containment building. A traditional technology of beryllium foil rolling has demerits that worsen its quality with decreasing of foil thickness. This leads to cost increasing of very thin foil (with a thickness of less than 50 micron).

By condition of hardening, strip is classified:

— soft;

— hard;

By length:

— specified;

— multiple to specific;

— random;
