Site by Infinity Arts. The following three alloys are included:. Precipitation Heat Treatment 9. The material for manufacture shall be cast and worked to such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure and specified temper in the finished product. Modulus of Elasticity Tension.

Alloys are used in a wide range of applications requiring very high strength and stiffness with good conductivity. Workmanship, Finish and Appearance If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

These products meet property requirements in Table 3 and normally require no further heat treatment by the user. Historical Version s – view previous awtm of standard. C The upper limits in the tensile strength column are for design guidance only.

Solution heat treated A Hard H all sizes up to 3? Additional sizes available, not all sizes shown are available from stock. This abstract is a brief summary of the referenced standard.

Within the text, the SI units are shown in brackets. C can develop more than ksi MPa tensile strength. Our staff of industry professionals is available to help you meet your metals requirements. Beryllium Copper Bar Future Metals is the premier source of high quality beryllium copper round bar.


The machinability rating of this alloy is Combining values from the two systems may result in nonconformance with the speci? Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 5 distributors but is also available to a lesser extent in Wire Products, and Flat Rolled Products.

Products shall be available in the following tempers: One is to be tested in the as-sampled condition, and one in the precipitation heat-treated condition.

The capacity for cold working this alloy is rated as “excellent”. We specialize in beryllium bar, but offer an additional selection of beryllium copper bar in a variety of additional specifications and offer cut to length programs from our strategically located facilities around the world.
