BJBH New Material is a new material company and mainly engaged in aluminum 3D printing powder materials, spherical aluminum powder materials and aluminum-based composite materials.
Aluminium alloy 3D printing powder material manufacturers cut into the metal 3D printing industry, gradually expanding metal 3D printing powder materials such as titanium alloys and superalloys, and equipped with metal 3D printers, with metal 3D printing material design and development verification, metal 3D printing processing services ability.
BJBH New Materials is committed to improving the quality of aluminum alloy 3D printing powder materials and expanding the types of aluminum alloy 3D printing powder materials. As of the end of 2018, AlSi10Mg (15 ~ 53um), AlSi10Mg (20 ~ 63um), AlSi7Mg (20 ~ 63um) and other 3D printing powders have been launched, which have won unanimous praise from customers in terms of product quality, quality stability and product service.
At the same time, for the 2019 TCT exhibition, a number of new varieties of aluminum alloy 3D printing powder were launched. The brief introduction is as follows:
1.A 3D printing powder with higher fluidity
This product mainly solves the problem that the domestic aluminum alloy powder has no Carney flow velocity or Hall flow velocity, which makes it unusable on equipment that requires high powder fluidity (such as SLM Solutions equipment). At the same time, the powder has higher fluidity, which helps better powder molding, improves print quality, and improves printing efficiency.
Product main performance indicators:
1) Granularity: 20 ~ 63um
2) Carney flow rate: 20 ~ 25s / 50g; Hall flow rate: 100 ~ 120s / 50g
3) Oxygen content: <1000ppm
3) Angle of repose: 30 ~ 35 °
4) Bulk density: 1.35 ~ 1.40g / cm3
2. AlSi7Mg (20 ~ 63um) 3D printing powder
AlSi7Mg (American Standard F357 alloy) is an aluminum-silicon alloy material suitable for the field of additive manufacturing. It has high strength, good plasticity, good corrosion resistance and excellent welding performance. It is suitable for metal 3D printing manufacturing Lightweight components and products in the aerospace, automotive, electronics and civil fields. Proven print mechanical properties (SLM process, print state):
Tensile strength: 430 ± 10MPa
Yield strength: 320 ± 10MPa
Elongation: 9.5 ± 1.0%
3. AlSi9Cu3 (20 ~ 63um) 3D printing powder
AlSi9Cu3 is an Al-Si series cast aluminum alloy, which has good high temperature and corrosion resistance, and has excellent application potential in the automotive industry and other fields. Proven print mechanical properties (SLM process, print state):
Tensile strength: 460 ± 20MPa
Yield strength: 290 ± 20MPa
Elongation: 9 ± 2%
4. AlSi12 (20 ~ 63um) 3D printing powder
AlSi12 is an Al-Si series cast aluminum alloy, which is suitable for applications that require good thermal conductivity and strain resistance. Proven print mechanical properties (SLM process, print state):
Tensile strength: 420 ± 20MPa
Yield strength: 290 ± 10MPa
Elongation: 10 ± 2%
