Desofin Additive Pat Applied for B2 Alloy. What we can found the smooth surface.
The Better Ductility.
The Potential Savings:
1. Savings over the cost of purchasing fine grained ingot.
2. Energy savings resulting from lower casting temperature.
3. Materials savings. It's not necessary to refine foundry scrap. I.E gates, risers and turnings already grain refined.

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. |

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. | |||||
