Bristol Brass (Prince’s Metal).
Оглавление—This alloy, which possesses properties similar to those of French brass, is prepared in the following proportions:
I | II | III | |
---|---|---|---|
Copper | 75.7 | 67.2 | 60.8 |
Zinc | 24.3 | 32.8 | 39.2 |
Particular care is required to prevent the zinc from evaporating during the fusing, and for this purpose it is customary to put only half of it into the first melting, and to add the remainder when the first mass is liquefied.
