· Ranked 5th in the 2025 Global Flake Aluminum Powder Brands with a score of 83.3—highest among Chinese peers

Targeting High-End Applications: Four Key Metal 3D Printing Powders
SUNRUNS is investing in its first phase with six gas atomization production lines, focusing on aluminum alloy powders for additive manufacturing and powder metallurgy. Its core products include AlSi10Mg, 316L stainless steel, high-strength aluminum alloys, and high thermal conductivity anodizable aluminum powders, catering to sectors such as aerospace, automotive, and marine manufacturing.

1. AlSi10Mg / AlSi7Mg Aluminum Alloys

· Process: Vacuum gas atomization

· Size: 15–53μm / 20–63μm

· Advantages: Excellent flowability, high sphericity, high tap/bulk density, cost-effective

· Applications: Lightweight 3D-printed parts, heat sinks, structural brackets, and prototypes

2. 316L Stainless Steel Powder

· Process: Nitrogen gas atomization

· Size: 15–45μm / 15–53μm

· Advantages: More affordable than vacuum atomized powder; better sphericity and oxygen control than water atomized powder

· Applications: Aerospace components, medical devices, auto parts, molds, and prototypes

3. High-Strength Aluminum Alloy – AlMgMnScZr

· Process: Vacuum gas atomization

· Size: 15–53μm / 20–63μm

· Advantages: High flowability, excellent sphericity, low crack sensitivity, tensile strength > 530 MPa

· Applications: Structural components for lightweight design, brackets, valve bodies

4. Anodizable & High-Thermal Conductivity Aluminum Powder – TAl300

· Process: Vacuum gas atomization

· Advantages: Good flowability, low crack sensitivity, moderate mechanical strength, anodizable, high thermal conductivity

· Applications: Aerospace, automotive, 3C electronics, and home appliances

Production Capacity Outlook: 10,000+ Tons by 2026
SUNRUNS currently has an annual output capacity of:

· 2,000 tons for powder metallurgy-grade aluminum alloys

· 600 tons for additive manufacturing-grade aluminum alloys

Phase II is already underway. By the end of 2026, the company aims to reach:

· 10,000+ tons for powder metallurgy aluminum alloy powders

· 2,000+ tons for additive manufacturing aluminum alloy powders

This massive capacity boost will further solidify SUNRUNS’s position in the metal 3D printing materials industry, ensuring a robust supply of high-quality raw materials for the growing market.

SUNRUNS’s strategic expansion into metal 3D printing is more than a business move—it signals a broader transformation for the industry. Backed by its technological leadership, massive capacity, and extensive market reach, SUNRUNS is poised to emerge as a key player in metal additive manufacturing. As its production scales and innovations advance, the industry can expect continued breakthroughs. Panda3dp.com will follow closely and bring you the latest developments.
