ERCuAl-A1: Built for Corrosion & Wear Resistance

ERCuAl-A1 aluminum bronze welding wire, supplied by XINXIN WELDING, is a copper-based alloy

classified under AWS A5.7, developed for welding and surfacing applications where corrosion resistance,

wear resistance, and stable mechanical performance are required.

The alloy typically contains approximately 7.0– 8.5% aluminum, with copper as the balance, providing

an effective combination of:

• Excellent seawater corrosion resistance

• High resistance to friction and cavitation wear

• Reliable mechanical performance under demanding service conditions

At XINXIN WELDING, our ERCuAl-A1 welding wire is manufactured for industrial users seeking stable

welding quality and consistent metallurgical performance.

Corrosion Resistance for Demanding Environments

One of the key advantages of XINXIN ERCuAl-A1 welding wire is its ability to perform in aggressive

environments.

The aluminum content forms a dense protective oxide layer on the weld surface, improving resistance

against:

• Saltwater corrosion

• Atmospheric oxidation

• Industrial chemical exposure

Because of these characteristics, ERCuAl-A1 from XINXIN WELDING is widely suitable for marine

equipment, offshore systems, and industrial repair applications.

Wear and Cavitation Resistance

Compared with conventional copper alloys, ERCuAl-A1 provides improved resistance to:

• Metal-to-metal wear

• Cavitation erosion

• Surface fatigue under repeated loading

Typical applications include:

• Pump components

• Propellers

• Bearings and bushings

• Valve seats and wear surfaces

Stable Welding Performance

XINXIN WELDING ERCuAl-A1 welding wire is designed to provide:

• Stable arc characteristics

• Smooth metal transfer
