Key applications: Rocket nozzles (W, Mo), radiation shielding (W), capacitors (Ta), biomedical coatings (Ta), superalloy additives (Re), nuclear (Nb)
Market note: Chinese refractory metal powder supply is globally significant. Spherical tungsten and tantalum powders are critical for defense and aerospace.

### Stainless Steel & Tool Steel Powders (Workhorse Materials)
Grades: 316L, 18Ni300 (Maraging Steel)
Typical density: 7.7-8.2 g/cm3
Production: VIGA atomization most common; EIGA for ultra-clean grades
Key applications: MIM injection molding, medical devices, tooling, high-strength maraging parts, food equipment
Market note: 316L is the most widely used metal AM powder globally. 18Ni300 maraging steel is prized for tooling and high-strength applications.

### Aluminum Alloy Powders (Lightweight Solutions)
Grades: AlMgZnCu (7xxx series high-strength)
Typical density: 2.66-2.82 g/cm3
Production: VIGA standard; moisture control critical (aluminum is hygroscopic and reactive)
Key applications: Automotive lightweighting, aerospace non-structural, heat exchangers, consumer products
Market note: AlSi10Mg dominates SLM aluminum. 7xxx series (AlMgZnCu) provides the highest strength for structural AM parts.

### Iron-Based Alloy Powders (Structural & Specialty)

Market note: High-purity copper powder is essential for electrical and thermal management applications in electronics.

### Precious Metal Powders
Grades: Silver (Ag) powder
Applications: Conductive pastes, electronics, photovoltaic cells
Market note: Silver powder for additive manufacturing is a high-value niche segment.

## Production Methods
1. **VIGA (Vacuum Induction Gas Atomization)** -- Most common for Fe/Ni/Co alloys. Clean melting, controlled chemistry.
2. **EIGA (Electrode Induction Gas Atomization)** -- Preferred for Ti alloys. No crucible contact = low oxygen.
3. **PREP (Plasma Rotating Electrode Process)** -- Premium spherical powders for aerospace. Highest sphericity.
4. **Plasma Spheroidization** -- For refractory metals (W, Mo, Ta). Irregular feedstock -> spherical.
5. **GA (Gas Atomization)** -- Standard for Al, Cu alloys. Cost-effective for high-volume production.

## Particle Size Standards by Application
- SLM / DMLS 3D Printing: 15-53 um (D10>15, D90<53)
- EBM (Electron Beam Melting): 45-106 um
- MIM (Metal Injection Molding): 0-20 um (fine powder)
- Laser Cladding / DED: 53-150 um
- HIP (Hot Isostatic Pressing): 53-150 um
- Thermal Spray: 15-45 um

## Business Process Flow
1. Buyer posts RFQ (material grade, particle size range, quantity, delivery timeline)
2. Platform auto-matches certified suppliers based on material capabilities
3. Suppliers submit quotations (unit price, MOQ, lead time, payment terms)
4. Buyer compares quotes, selects supplier, initiates contact
5. Both parties negotiate and sign electronic contract on-platform
6. Transaction completion, mutual rating (builds credit history)

## Credit Rating System
Suppliers are rated: AAA / AA / A / B / C
Evaluation criteria: transaction completion rate, quote response speed, product quality, on-time delivery, certifications held
