Weld Star – ER 120S-G TIG Wire (1.6mm) 5kg


SKU: 6031100490 Category: Tag: Brand:

Product Description

Features and Applications

A copper coated wire containing NiCrMo for welding ultra-high tensile strength steels.

Designed for fine grain steels exceeding 890 MPa yield strengths.

High impact strength at low temperatures with exceptional plasticity of the weld deposit.

Typically used on lifting and handling machinery, bridges, tanks, transport, shipbuilding, railway, mines, cranes, frames, etc.

Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
