Application Guidelines – Silicon Carbon Alloy 50-20 Powder
Silicon Carbon Alloy 50-20 powder is a high-performance material with the following primary applications:
Advanced Powder Metallurgy
Used in powder metallurgy blends for producing high-strength components. The 50% silicon content ensures efficient alloying during sintering, while 20% carbon provides carburization. Typical addition: 0.5-5% of powder blend depending on target composition.
High-Efficiency Injection Systems
Injected directly into molten steel via lance or wire injection. The higher silicon content allows lower addition rates to achieve target silicon levels, improving efficiency and reducing costs. Typical injection rates: 0.5-4 kg per ton of steel.
Premium Briquettes for Foundry
Compressed into briquettes with optimized binders for consistent addition in cupolas or electric furnaces. Ideal for foundries requiring precise silicon and carbon control.
Sintering of High-Performance Components
Used in sintering processes for automotive and engineering components, providing both alloying and carburization in a single additive.
Custom Alloy Blending
Mixed with other high-purity powders to create custom alloy formulations for specialized metallurgical applications.
Typical Addition Methods
Can be added via injection, as part of briquettes, or mixed with other materials. Our technical team can recommend optimal practices based on your equipment and process requirements.

Frequently Asked Questions – Silicon Carbon Alloy 50-20 Powder
Is it possible to entrust a third-party inspection to check the quality before shipment?
+
Certainly, we support third-party inspections by internationally recognized quality inspection agencies such as SGS and BV to verify product quality before shipment. The inspection covers product appearance, weighing, dimensions, and chemical composition analysis. The entire inspection process will be documented with photos and written records, which will be provided to you together with the final inspection report. This ensures you have no concerns regarding product quality.
What is the advantage of 50-20 powder over 40-20?
+
50-20 offers higher silicon content (50% min vs 40% min), providing more efficient deoxidation per unit weight. This allows lower addition rates to achieve target silicon levels, reducing overall material handling and potentially lowering costs. It is preferred for applications requiring higher silicon efficiency.
Can you supply 50-20 powder with tighter particle size distribution?
+
Yes, we can supply custom cuts such as 0-2mm, 0-5mm, or specific mesh sizes upon request. Please provide your target particle size distribution for a quotation.
Is 50-20 powder suitable for additive manufacturing?
+
While our standard 0-8mm powder is larger than typical AM powders, we can supply finer sizes (e.g., -100 mesh or -200 mesh) suitable for certain additive manufacturing and 3D printing applications. Please contact our technical team with your specific requirements.
How do you ensure consistent particle size distribution?
+
We use advanced screening equipment and conduct sieve analysis on every batch. A certificate of analysis including particle size distribution is provided with each shipment. Additional quality control measures can be arranged upon request.
Can 50-20 powder be used in cored wire?
+
Yes, 50-20 powder can be used as core fill for cored wire. We can optimize particle size distribution for wire filling and ensure consistent flow characteristics. Please discuss your wire specifications with our technical team.
