| AlSi 5 |
AWS: E 4043 DIN 1732: EL – AlSi 5 Current: = (+) / ~ |
Si:5 Others: max.0,15 Al: Rest |
Electrode for welding aluminum forging alloys and aluminum cast alloys. The weld deposit consists of an Al-alloy with 5% Si and is sufficient for almost all cast alloys. In case of alloys with higher Si-content, the Si-content in the weld deposit increases as well. Suitable for following base materials: |
T: 120 – 150 N/mm² Y: 55 – 78 N/mm² E(1=5d): 12 – 18 ————– H: 30 – 35 HB |
| AlSi 12 | DIN 1732: EL – AlSi 12 | – | For joining and surfacing of Al forging and casting alloys of the Al-Si, Al-Mg-Si, Al-Si-Mg-Cu types. Excellent welding properties, porosity-free joints and therefore perfect joining on plates from 2mm thickness. |
T: 200 – 240 N/mm² Y: 80 – 100 N/mm² E(1=5d): 3 – 6 % ———— H: 50 – 60 HB |
| Alu 99,8 |
DIN 1732: AL99,8 Current: = (+) |
Al: 99,8 Others: max.0,2 |
The electrode is used for joining and repairing of pure aliminium. According to the purity of the welding deposit of 99,8% Al, the corrison resistance is very good. The electrode has good welding properties with good slag removal. |
T: 80 – 90 N/mm² Y: 50 – 60 N/mm² E(1=5d): 25 – 30 % ————- H: 20 – 26 HB 10 |
| AlMn |
DIN 1732: ALMn Current: = (+) / ~ |
Mn: 0,8 – 1,5 Mg: 0,3 Al: Rest |
The electrode is used for joining and repairing of pure aliminium and aluminium alloys. The welding deposit is sea-water resistant and can be used for aluminate process with following materials: The electrode has good welding properties. |
T: 90 – 110 N/mm² Y: 40 – 60 N/mm² E(1=5d): 20 – 30 % ————- H: 20 – 30 HB 10 |
