标题: Zhongti New Materials Authorized to Produce BLT-AlAM400 Aluminum Alloy Powder and Sell It Overseas
Nanjixiong's introduction: China now has a metal-powder factory with capacity at the 10,000-ton scale that is authorized to manufacture and sell a metal alloy developed by another company.

On November 10, 2026, Nanjixiong learned that Anhui Zhongti New Materials Technology Co., Ltd. and metal AM leader Xi'an Bright Laser Technologies (BLT) reached a technical cooperation agreement. Zhongti received authorization to manufacture BLT's high-performance BLT-AlAM400 aluminum-alloy powder in China and sell it overseas, with exclusive authorization outside BLT and its regional agents. Using its independently developed atomization processes and 10,000-ton-scale capacity, Zhongti plans stable mass production of the alloy powder. It will offer integrated, cost-effective delivery from material and process through production for humanoid-robot structures, lightweight electric vehicles, aerospace parts, and other advanced manufacturing applications.

BLT-AlAM400: a strategic alloy balancing mechanical properties and printability

BLT-AlAM400 is a strategic aluminum-alloy powder developed by BLT for lightweight automotive structures, embodied-intelligence equipment, and advanced industrial applications. It balances strength, toughness, and stable high-temperature performance. Its overall mechanical performance is described as significantly better than conventional AlSi10Mg, making it suitable for lightweight parts in demanding environments.

1. Strong mechanical performance at room temperature

- Room-temperature tensile strength (Rm): approximately 460 MPa
- Yield strength (Rp0.2): approximately 390 MPa
- Elongation (A): approximately 10%
- Stable properties after heat-treatment strengthening, with excellent batch consistency
- Note: specimen data are for machined samples.

2. Stable mechanical properties over a wide temperature range

The material maintains a balance of strength and ductility at high temperatures, suiting it to high-temperature applications such as thermal-management components for new-energy vehicles and irregularly shaped pipes.

3. High-efficiency printing with thick layers, balancing density and productivity (BLT-S320 dual-laser system)

The system supports layer thicknesses from 30 μm to 150 μm. At 150 μm, build rate reaches 76.76 cm³/h, three times the rate at 30 μm. Density remains stable at 99.25%–99.95% across the full layer-thickness range, with very little hardness variation and uniform metallurgical quality in batch-printed parts. The process can substantially reduce porosity at greater layer thicknesses and mitigate the loss of mechanical properties that can accompany thicker layers.

4. Advantages in forming complex thin-wall structures

Powder spreading is smooth and fusion is stable, without a clear tendency toward hot cracking. The process can form thin-wall irregular pipes and hollow integrated housings with complex topologies that are difficult to produce by conventional machining, substantially reducing assembly steps.

Applications across multiple industries advance scaled production of lightweight AM parts

With its combination of strength and low weight, BLT-AlAM400 has entered batch applications in humanoid robots, new-energy vehicles, and aerospace piping, providing demonstration cases for the industry.

1. Core humanoid-robot housings: lightweight, load-bearing, and suitable for batch production

BLT-AlAM400 is used in key components such as humanoid-robot arm housings. It supports one-piece formation of complex structures. Each part weighs just 0.455 kg, integrating structures and reducing the robot's overall weight, which can increase payload and maneuverability without increasing energy consumption. Full-build batch printing on a 20-laser BLT-S800 takes only 58.6 minutes per part, 70% more efficient than a six-laser configuration, providing an efficient, low-cost, high-quality solution for large-scale production of robot parts.

2. Irregular thin-wall aerospace and hydraulic pipes

To address the complexity, cost, and forming constraints of conventional pipe bending, BLT-AlAM400 can directly print thin-wall pipes measuring 67 mm × 136 mm × 280 mm, integrating complex bends and internal channels while eliminating welding, bending, and multiple machining steps. The thick-layer process shortens production time. Parts are reported to be leak-free with uniform mechanical properties, suiting batch production of aerospace hydraulic lines and fluid pipes for low-altitude aircraft.

3. Aerospace and the low-altitude economy

Its high-temperature and fatigue performance and high density make BLT-AlAM400 promising for aerospace structures and low-altitude aircraft components.

A full portfolio of aluminum alloys

Zhongti has built a broad aluminum-powder portfolio. Its established production-grade AlSi10Mg is complemented by medium- and high-strength alloys covering 450–650 MPa; high-thermal-conductivity alloys with conductivity of at least 180 W/(m·K), combining conductivity, ductility, and corrosion resistance; and premium high-strength grades including Scalmalloy® EX, CNPC-Al0407, Scalmalloy® classic, CNPC-Al0436, CNPC-M1, and CNPC-Al34. Scalmalloy® offers excellent anodizing results and is described as the only domestically available material officially authorized by Airbus APWORKS. Across the portfolio, lightweighting is a major benefit, with maximum strength reaching 621 MPa. Applications span general industry, 3C consumer electronics, automotive, robotics, aerospace, new-energy vehicles, thermal management, motorsports, and high-end lightweight structures.

The company has obtained IATF 16949 automotive quality-management certification and SCS 100% recycled-material certification for certain alloys, creating a sustainable supply system.

Zhongti says it will continue improving powder-production processes and expanding domestic and overseas capacity, helping metal AM progress from prototyping toward large-scale industrial production.

Xi'an Bright Laser Technologies Co., Ltd. (stock code 688333) is a metal-AM full-solution provider offering equipment, printing services, feedstock, and technical services, with production-validated applications in automotive, robotics, and aerospace.

Anhui Zhongti New Materials Technology Co., Ltd. focuses on metal powders for additive manufacturing. It uses multiple powder-making methods including AMP, EIGA, PS, VIGA, PREP, and RDA, and exports to more than 40 countries. It says its process technology, consistent product quality, and production scale have made it a key materials supplier to advanced manufacturers worldwide.
