Grain refinement occurs when copper content is between 57 and 63 percent. Optimal grain refinement occurs when copper content is 59.5 percent and aluminum content is 0.6 percent. See Notes 1 and 2. |
| Leaded Yellow Brass (Over 17% Zn. Sn less than 6%. Under 2% total Al, Mn. Ni, Fe, Si. Pb more than 0.5%.) |

200 grams per metric ton (18 grams per 100 lb.) |
NO |
YES |
YES |
If high oxygen occurs, add Mn before adding DesofinTM. |

Tin Bronze (Sn 2% to 20%. Zn less than Sn. Pb under 0.5%) |
200 grams per metric ton (9 grams per 100 lb.) |
NO |
YES |
YES |
Use without Al tubes. Add to transfer ladle along with phos copper |
| Notes: 1. If Sn + Fe is greater than 0.5%, intermetallic compounds will form that will leave "comet tails" when casting is polished. 2. Miller & Englehardt Co., lltd recommends use of "B-2" yellow brass alloy with DesofinTM for permanent molding applications. B[1]2 alloy composition: Cu 59.5 to 61.5%; Pb 0% to 3.0%; Al 0.5% to 0.7%, Ni 1%; Sn + Fe 0.5 % max, Mn 0.02% max, Si 0.02% max, Zn balance. | |||||
