Manganese Metal 97% (abbreviated as 97% Manganese Ingot) is a high-purity metallic manganese product with a guaranteed manganese (Mn) content of 97.0–97.9% and strict impurity control (Fe≤1.0%, Si≤0.8%, C≤0.5%, S≤0.03%). Unlike lower-purity 95% Mn metal Ingot (with excessive impurities) or higher-purity 99% Mn metal Ingot (with premium costs), 97% Mn Metal fills the critical gap for mid-to-premium alloys-it meets the impurity requirements of 316 stainless steel, 6061 aluminum, and low-alloy structural steel while avoiding the 30–40% cost premium of ultra-high-purity grades. Available in lumps (5–50mm) or ingots (5–50kg), it ensures accurate dosing and stable dissolution, making it indispensable for manufacturers seeking to upgrade alloy quality without overspending.

Manganese Ingot is produced via electrolytic refining (primary method) or advanced pyrometallurgical purification, with a focus on balancing purity and cost. Its unique value for metallurgy lies in three critical traits:

Controlled High Purity: 97% Mn content eliminates "impurity dilution" in mid-premium alloys (e.g., 316 stainless steel, where Fe≤1.0% is required) while being 25–30% more cost-effective than 99% Mn metal.
Low Harmful Impurities: Fe≤1.0%, Si≤0.8% prevent brittle inclusions (e.g., Fe-Al-Si phases in aluminum alloys) and surface defects (e.g., oxide streaks in stainless steel), while C≤0.5% avoids carburization in low-carbon grades (e.g., 304L).
Versatile Physical Forms: Available as 5–50mm lumps (for batch feeding) or 5–50kg ingots (for precision dosing), adapting to both bulk steelmaking and small-batch alloy production.

These traits make 97% Manganese metal lump the most versatile choice for industries transitioning from mid-grade to premium alloys-such as automotive stainless steel components, aerospace aluminum extrusions, and low-alloy high-strength steel.

chemical composition

Parameter	Standard Range	Metallurgical Significance
Main Component	Mn: 97.0–97.9%	Ensures efficient alloying-reduces addition volume by 2–3% vs. 95% Mn metal, cutting raw material waste.
Key Impurities (Max.)	Fe: 1.0%, Si: 0.8%	Fe≤1.0% meets 316 stainless steel (Fe≤1.5% standard) and 6061 aluminum (Fe≤0.7%-compatible with low-Fe scrap blending).
	C: 0.5%, S: 0.03%	C≤0.5% is easily reduced to ≤0.03% via AOD refining (for 304L); S≤0.03% minimizes hot cracking in thick-walled castings.
	P: 0.02%, Pb: 0.002%	P≤0.02% avoids cold brittleness in cryogenic steel (e.g., 09MnNiDR); Pb≤0.002% meets food-contact stainless steel standards (FDA 21 CFR 177.2600).
Physical Forms	Lumps: 5–50mm; Ingots: 5–50kg	Lumps for bulk steel ladles; ingots for precision vacuum melting.
Quality Tolerance	Segregation: ≤0.3%	Minimal composition variation ensures batch-to-batch alloy consistency (scrap rate ≤2%).

Manganese metal ingot 97 use

Mainly used as alloy additive in steel smelting. Manganese is an important alloying element that can significantly improve the physical and chemical properties of steel.

Adding 97 manganese ingots can improve the hardness, toughness and wear resistance of steel, while improving the hot workability and corrosion resistance of steel.

Manganese ingot 97 effect

In the steelmaking process, 97 manganese ingots serve as reducing agents and deoxidants, helping to remove oxygen and sulfur from steel, reduce inclusions, and improve the purity of steel.

Manganese can also promote the dissolution and distribution of carbon, which is beneficial to the formation of uniform carbides, thereby improving the strength and wear resistance of steel.
