Easily Fusible Or Plastic Alloys.
Оглавление(These have a fusing point usually below 300° F.)
(See also Solders.)
I. Rose’s Alloy.—Bismuth, 2 parts; lead, 1 part; tin, 1 part. Melting point, 200° F.
II. Darcet Alloy.—This is composed of 8 parts of bismuth, 5 of lead, and 3 of tin. It melts at 176° F. To impart greater fusibility, 1/16 part of mercury is added; the fusing is then lowered to 149° F.
III.—Newton alloy melts at 212° F., and is composed of 5 parts of bismuth, 2 of lead, and 3 of tin.
IV.—Wood’s Metal.—
| Tin | 2 parts |
| Lead | 4 parts |
| Bismuth | 5 to 8 parts |
This silvery, fine-grained alloy fuses between 151° and 162° F., and is excellently adapted to soldering.
V.—Bismuth, 7 parts; lead, 6 parts; cadmium, 1 part. Melting point, 180° F.
VI.—Bismuth, 7 to 8 parts; lead, 4; tin, 2; cadmium, 1 to 2. Melting point, 149° to 160° F.
