SPECIAL ALLOYS FOR MOULDS WELDURAL® WeLdural® has been developed to provide the best possible mechanical stability over a temperature range of up to 250°C. Even when exposed to heat for over 1,000 hours, the resistance is significantly higher than that of 7075 alloy. Information transcribed from the supplier datasheet. MAIN CHARACTERISTICS • Very good thermal conductivity • Excellent electrical conductivity • Greater thermaL stability • Excellent dimensional stability • Very good machining and poLishing • High wear resistance • Extremely uniform mechanical properties • Excellent weldability • Good resistance to corrosion APPLICATIONS • Injection and blow moulds • Moulds for high temperature parts # High precision mechanicaL parts (requires high dimensional stability) • Moulds with welded constructions • Refrigeration engineering • Machine elements All figures given are indicative onLy, Polylanema Lda. is not liable for the use of the materials without consulting with our technical depart
