Beryllium Copper Standard

Safety and Health Topics | Beryllium | Occupational Safety ...

Beryllium alloys are classified into two types: high beryllium content (up to 30% beryllium) and low beryllium content (2 - 3% beryllium). Copper-beryllium alloy is commonly used to make bushings, bearings, and springs. Beryllium is also found as a trace metal in slags and fly ash.

Resources: Standards & Properties - Copper & Copper Alloy ...

There are two groups of copper beryllium alloys, high strength alloys and high conductivity alloys. The wrought high strength alloys contain 1.6 to 2.0% beryllium and approximately 0.3% cobalt. The cast, high-strength alloys have beryllium concentrations up to 2.7%.

Standard Specification for Copper-Beryllium Alloy Plate ...

1.1 This specification establishes the requirements for copper-beryllium alloy plate, sheet, strip, and rolled bar. The following alloys are specified: 2.

Guide To Beryllium Copper - Michigan State University

Beryllium copper high strength alloys are less dense than conventional specialty coppers, often providing more pieces per pound of input material. Beryllium copper also has an elastic modulus 10 to 20 percent higher than other specialty copper alloys. Strength, resilience, and elastic properties make beryllium copper the alloy of choice. 6

Beryllium Copper Alloys

beryllium nickel or copper, can cause hardening of the alloy structural precipitation annealing treatment at low temperature. The copper beryllium alloys are produced from a master alloy of copper and beryllium, containing approximately 4 % of beryllium. The manufacturing process is as follows:

OSHA has released a new beryllium standard for General ...

In this article, we will take a closer look at this new beryllium standard and compliance requirements. Although the new standard seems rather in-depth and complex, it’s really not that bad. First, a little background. Beryllium is a light-weight metal that isn’t found naturally as a stand-alone metal.

AT0015 0311 Heat Treating Copper Beryllium Parts

copper beryllium varies from 500°F (260°C) to 700°F (370°C). The time required to reach peak properties at the lower temperature is longer than at the higher temperature.

Beryllium copper - Wikipedia

Beryllium copper attains the greatest strength (to 1,400 MPa (200,000 psi)) of any copper-based alloy. It has good thermal conductivity (62 Btu/ft-deg.F-H) 3-5 times more than Tool steel. Toxicity [ edit ]

Beryllium Safety: OSHA compliance guidance & safety resources

beryllium safety Materion is an advanced materials supplier and is the world’s only fully integrated developer and supplier of beryllium (Be), beryllium alloys and beryllium composites.

NGK Berylco | World leader in Beryllium Copper

While many nonferrous alloys meet nonsparking standards, only beryllium copper has the superior strength and hardness not found in safety tools made from aluminum, bronze, and brass. The nonmagnetic and corrosion-resistant properties of our tools are well suited for industrial and high technology applications.

Beryllium OSHA Standard Revisions | Fume Extractors

Jun 15, 2018 · Beryllium is used as a pure metal, beryllium oxide or made into an alloy with copper, aluminum, magnesium and nickel 3. Beryllium oxide has a high capacity of heat making it an essential component of sensitive electronic equipment. Beryllium copper with just 2% beryllium provides a material that is six times stronger than copper alone 2.

Beryllium Copper Supplier | Mead Metals in Minnesota

Beryllium Copper Product Specifications Our beryllium copper meets ASTM B194 specifications and is ideal for an array of applications. Beryllium copper, commonly referred to as BeCu and Alloy 25, exhibits superb electrical and thermal conductivity. It is extremely ductile, and as such can be stamped into complex shapes with tight tolerances.


Airborne particles of beryllium alloys can, if inhaled to excess, cause irreversible lung damage in people who are sensitive to beryllium. Prevention of this adverse health effect (called berylliosis or, more precisely, chronic beryllium disease) lies in maintaining good air quality.

Final Rule to Protect Workers from Beryllium Exposure ...

OSHA estimates that the rule will save 90 lives from beryllium-related diseases and prevent 46 new cases of chronic beryllium disease each year, once the effects of the rule are fully realized. The rule is projected to provide net benefits of about $560.9 million, annually.

Safety Practices for Machining Copper Beryllium Alloys ...

In addition, processing copper beryllium alloys shall be conducted in accordance with the Beryllium Standard for General Industry (29 CFR 1910.1024) established by the Occupational Safety and Health Administration (OSHA) which includes a Permissible Exposure Limits (PEL) of 0.2 microgram beryllium per cubic meter (0.2 µg/m3) as an 8-
