Understanding Sone 385
Sone 385 is a metal alloy grade, often classified in the category of zinc-based alloys or specialized die-casting alloys. The designation “385” indicates a particular standardized composition that differentiates it from similar grades like 380, 390, or 383. Each grade serves different functional needs in terms of machinability, corrosion resistance, wear properties, and tensile strength.
In simple terms, Sone 385 is engineered for applications that require moderate-to-high strength while ensuring good dimensional accuracy during casting and machining. It is also known for offering a balanced trade-off between cost efficiency and performance, which is why industries prefer it over certain higher-cost alloys.
Composition of Sone 385
The alloy composition of Sone 385 consists primarily of zinc, but it is carefully blended with other elements to enhance its strength, machinability, and corrosion resistance. The most common elements present in its structure include:
| Element | Approximate Percentage | Role in Alloy |
|---|---|---|
| Zinc (Zn) | 85 – 90% | Base material, provides structural foundation and corrosion resistance. |
| Aluminum (Al) | 3 – 4% | Improves strength, enhances hardness, and stabilizes the structure. |
| Copper (Cu) | 2 – 3% | Increases wear resistance and overall durability. |
| Magnesium (Mg) | 0.05 – 0.1% | Provides stability against corrosion and improves creep resistance. |
| Iron (Fe) | 0.05 – 0.1% | Helps control brittleness and grain structure. |
| Others (Trace) | <0.05% | Includes nickel, silicon, or tin depending on manufacturing standards. |
This balanced composition makes Sone 385 a versatile material for industrial casting and machining.
