AK-ERCuZn-D TIG and MIG Wire for Cast Iron and Copper Alloy Welding.
A copper-zinc-nickel alloy wire designed for surfacing and butt welding of cast iron, copper alloys, and nickel alloys with good corrosion resistance and mechanical strength.
Product Overview
AK-ERCuZn-D (TIG / MIG) is a copper-zinc-nickel alloy welding wire used in TIG and MIG welding processes for machinery manufacturing, automation, steel furniture, and other industrial applications.
It is suitable for surface anti-corrosion surfacing on cast steel, gray cast iron, copper alloy, and nickel alloy components, as well as for butt welding of gray cast iron joints.
The wire meets EN ISO 24373 CuZn40Ni10Sn1 and AWS A5.7 ERCuZn-D GB/T 9460 CuZn40Ni10Sn1 standards, with a chemical composition tailored for corrosion resistance and mechanical performance.
Application: It is used in machinery manufacturing, automation industry, steel fur niture and other industries. It is used for surface anti-corrosion surfacing welding of cast steel, gray cast iron, copper alloy and nickel alloy parts. It is also suitable for butt welding of gray cast iron.
Key Benefits
Corrosion-Resistant Surface Layer
The nickel and zinc content in AK-ERCuZn-D provides enhanced resistance to corrosion when used for surfacing on cast iron and copper alloy parts.
Good Mechanical Properties
The deposited metal achieves a tensile strength of 385 N/mm² and elongation of 25 percent, supporting structural integrity in service.
Suitable for Gray Cast Iron Welding.
The wire is specifically recommended for butt welding of gray cast iron, helping to reduce cracking during solidification.
Stable Melting Range
With a solidus temperature of 890℃ and liquidus temperature of 935℃, the wire maintains consistent flow during welding and solidifies with minimal distortion.
Where It Is Used
- Surface anti-corrosion surfacing on gray cast iron and copper alloy components.
- Butt welding of gray cast iron joints in machinery and industrial equipment.
- Welding of cast steel and nickel alloy parts requiring corrosion resistance.
- Repair and fabrication in automation and steel furniture industries.
Who It Is For
