More info

Chromium Powder is a grey refractory metal powder produced with advanced smelting and powder processing technologies. It is an essential raw material for high-end manufacturing industries. It has two primary categories, including spherical chromium powder and irregular chromium powder. HM is committed to providing the most suitable chromium powder product and solution for your specific application needs.

Chromium Powder, Cr Powder, CAS 7440-47-3

Spherical Chromium Powder: Spherical chromium powder is widely used in 3D printing, additive manufacturing, laser cladding, and injection moulding due to its excellent flowability.
Irregular Chromium Powder: Irregular chromium powder is made from degassed electrolytic chromium plates, which are then crushed to obtain chromium powder in various sizes. It is primarily used for high-purity chromium sputtering targets, chromium alloys, and various additives.

Note:

The mass fraction of chromium is calculated as 100% minus the total measured content of impurities in the table (excluding gaseous elements). Individual elements not listed are less than 5 ppm.
Custom metal chromium powders with specific particle sizes can be made according to customer requirements. The commonly used particle size range is 45-180 μm, with special fine powders based on actual test results.
Metal chromium powders with different chemical compositions can be customised according to customer requirements.

Chromium Powder Features

Comprehensive Grades: Available in multiple purity levels (e.g., 99.95%, 99.5%) to meet diverse requirements from R&D to industrial production.
Low Gas Content: Specially optimised "low-gas" grades feature excellent control over oxygen and nitrogen content, ensuring performance stability in high-temperature applications.
Stringent Impurity Control: Key impurity elements such as Fe, Al, Si, S, and C are strictly controlled to guarantee consistent end-product performance.
Adjustable Particle Size: Powders are available in various particle size ranges, from micron-level to specific distributions, based on customer needs.
Superior Morphology: The powder particles exhibit regular morphology, ensuring good flowability and packing density.

Chromium Powder Applications

Superalloys: Serves as a crucial alloying element in manufacturing nickel-based and cobalt-based superalloys, widely used in components like jet engines and gas turbine blades.
Speciality Steels: Used as an additive in producing stainless steel, tool steel, and other alloy steels to significantly enhance hardness, strength, wear, and corrosion resistance.
Surface Coatings: Applied via thermal spray techniques (e.g., plasma spray) to form wear-resistant and corrosion-resistant chromium coatings on workpiece surfaces.
Electronics & Targets: Used in the fabrication of chromium sputtering targets for thin-film deposition, applied in microelectronics, flat-panel displays, and solar cells.
Welding Materials: Acts as an alloying agent in welding electrode coatings for the repair and manufacturing of wear-resistant and corrosion-resistant components.
Chemical Catalysts: Function as a catalyst or catalyst support in various chemical synthesis reactions.

Chromium Powder Packing And Shipping

The Chromium Powder are securely packed in wooden crates or cartons, reinforced with cushioning materials to prevent movement during transit. This packaging approach ensures that the products remain intact and protected throughout the shipping process.
