product introduction

The copper-based alloy with aluminum as the main alloying element is aluminum bronze containing iron and manganese elements, and is a high-strength and heat-resistant bronze.

1、The core advantages of aluminum bronze

Features	Description
Ultra-high strength	The tensile strength can reach 500~1000 MPa, which is close to some steels and much higher than ordinary brass.
Excellent wear resistance	The hardness can reach HB 200~300, suitable for high friction environments (such as bearings, gears).
Extremely corrosion resistant	Resistant to seawater, acid and alkali corrosion, especially in chlorine-containing environments (such as ships and chemicals).
Fatigue and creep resistance	Remains stable at high temperatures (operating temperature can reach 400°C).
Spark-free characteristics	No sparks are generated when colliding, and it is used in flammable and explosive environments (such as oil and mining equipment).

2、Common brands and uses (classified by standard)

Material Grade	Element	Features and uses
QAl9-4	Cu+Al 8.0~10.0%, Fe 2.0~4.0%	High strength and wear resistance, used for ship propellers and valves.
QAl10-4-4	Cu+Al 9.5~11.0%, Fe 3.5~5.5%, Ni 3.5~5.5%	High temperature corrosion resistant, aircraft engine parts.
QAl7-2	Cu+Al 6.0~8.5%, Mn 1.5~2.5%	Free-cutting, precision mechanical parts.
ASTM C95400	Cu+Al 10~11.5%, Fe 3.0~5.0%	For heavy-duty bearings.
EN DIN CuAl10Fe5Ni5	Nickel content improves corrosion resistance	Chemical pumps and valves.

3、Typical application scenarios

Hydraulic industry: water pumps, valves

Shipbuilding industry: propellers, seawater pump shafts, submarine pipelines.

Chemical equipment: acid-resistant pumps and valves, reactor linings.

Aerospace: landing gear bearings, engine sealing rings.

Energy mining: spark-free tools, oilfield valves.

Aluminum bronze is a copper alloy with top comprehensive properties in strength, corrosion resistance and wear resistance, suitable for extreme working conditions. If an alternative is needed (such as cost-sensitive scenarios), manganese brass (HMn62-3) or tin bronze (QSn6.5-0.1) can be considered, but the performance loss needs to be weighed.
