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:
G-AlSi 7, AlSi 5 Mg

T: 120 – 150 N/mm²

Y: 55 – 78 N/mm²

E(1=5d): 12 – 18

————–

H: 30 – 35 HB

Table separator
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:
Al99,5, Al99, Al98, AlMn, AlMgMn, AlMg1, AlMg2

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
