Can Toyal JWX customize the particle size distribution of aluminium powder?

Yes. Particle size distribution, alloy composition and surface treatment can be engineered to the customer's process, whether laser powder bed fusion, metal injection molding, press-and-sinter powder metallurgy, thermal fillers or pigment milling.

What is the difference between spherical and coated aluminium powder?

Spherical uncoated powder offers high flowability and packing density for 3D printing, PM and AMMC. Coated or surface-treated aluminium powder adds a functional surface layer that improves compatibility with polymer matrices such as silicone or epoxy and improves handling behaviour in thermal filler formulations.

How is aluminium powder shipped internationally?

Aluminium powder is a regulated dangerous good. Uncoated aluminium powder is typically classified as UN1396 (Class 4.3) and coated aluminium powder as UN1309 (Class 4.1). It is shipped in sealed, inert-protected packaging with Safety Data Sheets and compliant dangerous-goods documentation.

Which quality certifications does the factory hold?

The company is certified to ISO 9001:2015 Quality Management System and ISO 14001:2015 Environmental Management System, and holds a Safe Production License for metal powder manufacturing.

What is Toyal JWX's relationship with Toyo Aluminium?

Founded in 1997, Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. was jointly acquired in December 2009 by Toyo Aluminium K.K. Group and Shanghai Matsuo Co., Ltd., bringing Japanese process discipline and quality control to its aluminium powder production.

Famous Uncoated Aluminum powder for thermal management products Supplier, TOYAL

TJWX obtains more than twenty years of experience for producing spherical aluminum powder, which enables goods stable and safely produced in the plant.

TJWX produced spherical aluminum powder with uncoated type; It is silver gray, and it is made by aluminum ingot(Al>99.8%) via melting by furnace under high temperature and high pressure, and the material produced by aluminum powder became got light weight. It would also be a good choice because of its good compatibility with loading carrier and low thermal impedance.
