- Weldable materialAluminum
Covering type: salt.
Electrodes for welding of alloys on the basis of aluminum, aluminum molding with the content of silicon to 12% of the type AlSi12, AlSi10Mg (Cu), AlSi9Mg.
It is suitable for the repair purposes. The remains of slag have to be removed to guarantee corrosion resistance of a layer of the built-up metal.
Current sort: constant (+)
Alyumo - a silicon electrode with the content of silicon of 12%.
- The flux covering of an electrode created by a pressing method provides big service life and the increased moisture resistance.
- It can be made in various standard flowers.
- Are packed into tight aluminum jars or vacuum folginirovanny packages for increase in period of storage.
