QuAl99,5 Bobbin – Laser Welding Wire Pure Aluminium Al99.7 / ER1070 (3.0259)
QuAl99,5 is the pure aluminium wire: EN ISO 18273 S Al 1070 (Al99.7) · AWS ER1070 · material no. 3.0259.
The high purity is not incidental here but the point: it provides the good chemical resistance for which pure aluminium is used in the first place — in plant engineering, chemistry and electrical engineering. As cast the deposit is soft (Rm 65 MPa); strength can be raised by cold working, not by heat treatment.
Recommended base materials
- Pure aluminium
- Al99.5, Al99.7 and similar
Typical applications
- Repairs on pure aluminium semi-finished products
- Chemical plant construction
- Components requiring chemical resistance
- Electrical engineering
Properties and advantages
- High purity → good chemical resistance
- Soft as cast, can be strengthened by cold working
- Re 20 MPa · Rm 65 MPa · A 35 % — very ductile
