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.
