Most of the industrial beryllium is made of beryllium beads produced by magnesium reduction as raw materials.
amount, grain size, and heat treatment and molding processes to obtain products with different properties.
The metal beryllium beads obtained by the thermal reduction of beryllium oxide magnesium are silver-grey and are used as beryllium products
raw materials.
The detection shows that the world’s beryl reserves are 1.21 million tons (calculated as beryllium), and the average
Calculated at 1450 tons per year, it can be mined for more than 800 years.
Mechanical properties of beryllium Light metal beryllium has many unique physical and mechanical properties, its tensile strength
Strength greater than or equal to 320MPA, yield strength 220MPA, elongation 2%, elastic modulus

Beryllium alloys Beryllium alloys mainly fall into the following categories:
Beryllium aluminum alloy, beryllium nickel alloy, beryllium cobalt alloy, beryllium copper alloy and other categories.
Among them, beryllium copper alloy accounts for 70% of the consumption of beryllium, and beryllium copper alloy is divided into:
Beryllium bronze, beryllium nickel copper, beryllium cobalt copper, etc.
Among them, beryllium bronze has the most excellent performance and is the most widely used.
The following focuses on beryllium bronze.
Beryllium bronze is a precipitation hardening alloy that is mechanically, chemically, and corrosion resistant
The only non-ferrous alloy with good combination of properties, after solution and aging heat treatment, it has
Special steel has high strength limit, elastic limit, yield limit and fatigue limit, and at the same time has high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance,
It also has good casting properties, non-magnetic properties and no sparking when impacted.
Therefore, it can be widely used in electronic appliances, communication instruments, aerospace, petrochemical
Industry, metallurgical mining, automotive appliances, machinery manufacturing and other fields.
