QAl10-4-4	Al 9.5~11.0%, Fe 3.5~5.5%, Ni 4.0~5.5%	High temperature corrosion resistant, aircraft engine bearings, chemical pump parts.
QAl7-2	Al 6.0~8.5%, Mn 1.5~2.5%, Cu balance	Free cutting, precision gears and bushings.
ASTM C95400	Al 10~11.5%, Fe 3.0~5.0%	Heavy machinery bearings and gears.
EN DIN CuAl10Fe5Ni5	Al 8.5~11.0%, Fe 4.0~6.0%, Ni 4.0~6.0%	Seawater corrosion resistant parts.

2、Core Properties of Aluminum Bronze Rods

Performance	Value/Characteristics	Advantages
Tensile Strength	550~1000 MPa (close to alloy steel)	2~3 times higher than ordinary brass (H62).
Hardness	HB 200~300 (can be heat treated and strengthened)	The wear resistance is better than 304 stainless steel.
Corrosion resistance	Resistant to seawater, sulfuric acid, hydrochloric acid, and alkali	More resistant to chloride ion corrosion than 316L stainless steel
High temperature resistance	Long-term working temperature ≤400°C	Maintains high strength even at high temperatures.
No spark	Collision does not produce sparks	Suitable for explosion-proof tools in petroleum and mining.
Electrical and thermal conductivity	Electrical conductivity 15~25% IACS (lower than pure copper)	Still better than steel.

3、Common specifications of aluminum bronze rods

Parameter	Common specification range	Remark
Shape	Round rods, square rods, hexagonal rods, special-shaped rods	Support customized non-standard sizes.
Diameter/side length	Φ5mm~Φ300mm (round bar)	Larger sizes usually require hot rolling or forging.
Length	1m~6m (straight strip) or rolled stick (can be coiled)	The coiled rod is suitable for continuous CNC processing.
Surface state	Hot rolling (R), cold drawing (Y), forging (F)	The accuracy of cold drawn bars can reach ±0.05mm.

4、Typical applications of aluminum bronze rods

Industry Specific applications Core performance matching

Shipbuilding industry Propeller shafts, seawater pumps and valves, rudder bearings Seawater corrosion resistance + high load

Chemical equipment Acid-resistant pump shafts, reactor agitators Chemical corrosion resistance + wear resistance

Energy mining Oilfield valves, explosion-proof tools No sparks + high strength

Aerospace Landing gear bearings, engine sealing rings High temperature resistance + fatigue resistance

Machinery manufacturing High-load gears, bearings, hydraulic valve stems Wear resistance + impact resistance

Aluminum bronze rods are top-grade copper alloy materials with high strength, corrosion resistance and wear resistance, especially suitable for harsh environments such as ships, chemicals, and energy. When purchasing, you need to pay attention to the grade, composition, surface quality, and choose a reliable supplier. If you need specific grade recommendations or processing parameter optimization, you can provide detailed application scenarios (such as load, medium, temperature, etc.) for further consultation!
