Beryllium Mining | Processing Equipment | Flow Chart
Beryllium. Description. Beryllium (Be) is a silver-white and very light metal. It has a very high melting point at 2349 °F (1287 °C). It is found in nature primarily as bertrandite, which is mined in Utah, or as beryl. The combination of its light weight and high melting point makes it valuable for making metal alloys which are used in ...
How to Heat treat Beryllium Copper
That translates to roughly 37-38 Rockwell C. If your beryllium copper is C17200 alloy, you can get there with a 2 hour at 600 °F aging treatment. If it is C17000, you can get in that range, but I wouldn't bet on a 79 minimum: probably closer to 77. If you've got C17410, C17500, or C17510, you'd better hope that you're being asked for the 30T ...
Beryllium Extraction and Beneficiation
Unlike aluminum, it resists corrosion by salt water, etc. Its rate of expansion with heat is the same as that of cast iron. It alloys easily with aluminum. An alloy of beryllium 70% and aluminum 30%, is one-fifth lighter than aluminum, and resists corrosion much better. In tensile strength it greatly exceeds duralumin.

Beryllium Bronze
Introduction. Bronze with beryllium as the main additive element. The beryllium content of beryllium bronze is 0.2% to 2%, and a small amount (0.2% to 2.0%) of the third component of cobalt or nickel is added. The alloy can be strengthened by heat treatment. It is an ideal high-conductivity, high-strength elastic material.
Long term operation of a 30 kW Beryllium target at IPHI
Long term operation of a 30 kW Beryllium target at IPHI. Following tests of low power bulk Beryllium targets in 2016–2020, a high power target was designed, built and tested at the High Intensity Proton Injector (IPHI) at CEA Paris–Saclay. The design of the target and the results of the tests will be described.
