Product Details beryllium beryllium copper as the main alloying
element in copper alloy, also known as bronze.
It was the best performance copper alloys senior elastic material,
has high strength, elasticity, hardness, fatigue strength, elastic
hysteresis, corrosion, abrasion, cold, high-conductive,
non-magnetic, shock does not produce sparks a series of excellent physical, chemical and mechanical properties.
Edit this paragraph classification processing beryllium copper
beryllium and beryllium bronze casting of the points.
Cast bronze are used Cu-2Be-0.5Co-0.3Si, Cu-2.6Be-0.5Co-0.3Si,
Cu-0.5Be-2.5Co like. Processing beryllium beryllium content of 2% or less, domestic
beryllium copper, 0.3% nickel, or cobalt plus 0.3%.
Processing bronze are used: Cu-2Be-0.3Ni, Cu-1.9Be-0.3Ni-0.2Ti
Beryllium is heat strengthened alloys.
Beryllium is mainly used for a variety of advanced processing and
flexible components, especially the requirements of good
conductivity, corrosion resistance, abrasion resistance, cold
resistance, non-magnetic variety of components for a large number
diaphragm, diaphragm, bellows, micro switch and so on.
Casting bronze is used for explosion-proof tools, various molds,
bearings, bearings, bushings, gears, and a variety of electrodes.
Beryllium oxides and dust harmful, production and use should pay
attention to protection.
Beryllium copper is the mechanical, physical, chemical, good
overall performance of an alloy, hardened after quenching, high
strength, flexibility, abrasion resistance, fatigue resistance and
heat resistance, and beryllium copper also has high electrical
conductivity resistance, thermal resistance, cold resistance and non-magnetic,
crashing when no spark, easy welding and brazing, in the
atmosphere, freshwater and seawater corrosion resistance is
excellent. Beryllium copper alloy corrosion in seawater velocity:
(1.1-1.4)10-2mm / years. Corrosion Depth: (10.9-13.8)10-3mm / years. Corrosion, strength, elongation did not change, it is also the
water can be maintained at more than 40 years, is a submarine cable
repeater structure irreplaceable material. In sulfuric acid medium: in less than 80% concentration of sulfuric
acid (at room temperature) the corrosion depth of 0.0012-0.1175mm,
concentrations greater than 80% is slightly accelerated corrosion.
Edit this paragraph performance parameters of beryllium copper is a
supersaturated solid solution copper alloys, mechanical properties,
physical properties, chemical properties and good corrosion
resistance combined with non-ferrous alloy, after solution and
aging treatment, with a special steel equivalent high ultimate strength, elastic limit, yield strength and fatigue
limit, but also have a high electrical conductivity, thermal
conductivity, high hardness and wear resistance, high creep
resistance and corrosion resistance, widely used in the manufacture
of various types of mold inserts parts, replacement of steel production of high precision, complex
shape of the mold, welding electrode materials, die-casting,
injection molding machine punch, wear and corrosion work. Beryllium copper used in micro-motor brush, cell phone, batteries,
products, is an important and indispensable national economic
construction industrial materials.

Edit this section uses high performance beryllium copper beryllium
copper mainly around the non-ferrous metal pressure, gravity
casting mold using a variety of conditions, through in-depth
research bronze mold material failure causes fluid composition and
erosion resistant metal inner relationship, the development of high
conductivity (heat), high strength, wear resistance, high temperature
resistance, high toughness, corrosion-resistant metal combined with
high performance liquid bronze mold materials, non-ferrous metals
to solve the domestic pressure, gravity casting mold easy to crack
and wear problems , significantly improve die life, speed, and casting mold strength;
overcome liquid slag adhesion and corrosion of
