Note thermic treatment for maximal values Suitable for material Nos.: Aluminium materials up to F30 Welding filler JOKE® Fill 255 - TIG Design Dimensions Weight Order No. Price * Al-Mg-Mn-Cu filler. For wrought aluminium alloys Rods 500 mm Ø 1.6 mm 1.000 0 084 464 from F 28 to F 53. Condition-changing through cold and hot aging. Increased hardness achievable through compression hardening. Particularly suitable for repairs on plastic moulds and tool inserts. The hardness is dependent on the composition to the parent material and can vary between approx. 280 - 420 N/mm depending on the condition. Suitable for material Nos.: Aluminium materials F28 and above Welding filler JOKE® Fill 242 - TIG Design Dimensions Weight Order No. Price * Cu-Ni-Si filler with good conductive characteris- Rods 500 mm Ø 1.6 mm 1.000 g 0 085 004 tics. Loy-specific colour characteristics. Intensive cooling from -20 °C results in improved hardness by up to 30%. Suitable for joining copper/bronze with steel. Hardness first layer: approx. 60 - 84 HB. Expansion approx. 23 - 32 %, tensile strength approx. 200 - 280 N/mm2.
