How to distinguish between beryllium bronze and aluminum bronze?

Bronze has high elasticity and fatigue, excellent wear resistance and corrosion resistance, good electrical and thermal conductivity, non-magnetic, and no sparks when impacted. Beryllium bronze is mainly used to make important springs for precision instruments, clock gears, bearings and bushings working under high speed and high pressure, as well as welding machine electrodes, explosion-proof tools, nautical compasses and other important parts.

Copper-based alloys with aluminum as the main alloying element are called aluminum bronzes. The mechanical properties of aluminum bronze are higher than those of brass and tin bronze. The aluminum content of the practical aluminum bronze is between 5% and 12%, and the aluminum bronze with aluminum content of 5% to 7% has good plasticity and is suitable for cold working. When the aluminum content is greater than 7% to 8%, the strength increases, but the plasticity decreases sharply, so it is mostly used in the as-cast state or after hot working.

Precipitation hardening alloy, with high strength, hardness, elasticity and fatigue after solution aging treatment, small elastic hysteresis, and corrosion resistance (corrosion resistance rate in seawater: (1.1-1.4) × 10-2mm/year. Corrosion Depth: (10.9-13.8)×10-3mm/year.) After corrosion, the strength and elongation of the alloy have no change, so it can be maintained in seawater for more than 40 years. For beryllium bronze products, beryllium copper alloys are submarine cable relays Irreplaceable material for device construction.

Beryllium bronze has the characteristics of wear resistance, low temperature resistance, non-magnetic, high electrical conductivity, and no sparking when impacted. It also has good fluidity and the ability to reproduce fine patterns. Due to the many superior properties of beryllium copper alloy, it has been widely used in manufacturing.

Precipitation hardening alloy, with high strength, hardness, elastic limit and fatigue limit after solution aging treatment, small elastic hysteresis, and corrosion resistance (corrosion resistance rate in seawater: (1.1-1.4) × 10-2mm/year .Corrosion depth: (10.9-13.8)×10-3mm/year.) After corrosion, the strength and elongation of the alloy have no change, so it can be maintained in seawater for more than 40 years. For beryllium bronze products, beryllium copper alloys are submarine cables. An irreplaceable material for repeater construction. In sulfuric acid medium: in sulfuric acid with a concentration of less than 80% (room temperature), the annual corrosion depth is 0.0012-0.1175mm, and the corrosion is slightly accelerated when the concentration is greater than 80%.

The hardness is between (HRC) 38-43, the density is 8.3g/cm3, and the beryllium content is 1.9%-2.15%. It is widely used in the inner inserts, mold cores, die-casting punches, hot runner cooling systems, etc. of plastic injection molding molds. Thermal nozzle, integral cavity of blow mold, automobile mold, wear plate, etc.
