Abstract
The invention relates to a novel palladium-based alloy. This palladium-based alloy comprises tin in an amount, preferably of 5 to 20% by weight, which is sufficient to impart an acceptable resistance to corrosion by molten glass, preferably being essentially equivalent to that of platinum-rhodium 10% alloys. An alloy of this type can be used in the glass industry for making components which come into contact with molten glass, which preferably essentially contains no oxides less stable than tin oxide, such as lead oxide, because it has an excellent resistance to corrosion by molten glass and is much less expensive than the platinum-rhodium 10% alloy normally used. Moreover, by the addition of at least one element selected from platinum (0-50% by weight), rhodium (0-20% by weight), iridium (0-20% by weight) and ruthenium 0-20% by weight), the mechanical strength at high temperature, especially the creep strength, is significantly improved.
