Overview of China Hastelloy c276 Alloy Nickel nickel-molybdenum-chromium superalloy Sheet steel plate hastelloy c22

Metal powder is a common form of metal that has been processed into fine particles, ranging from a few micrometers to over 100 microns in diameter. It plays a crucial role in various industrial applications due to its unique properties and versatility.

Features of China Hastelloy c276 Alloy Nickel nickel-molybdenum-chromium superalloy Sheet steel plate hastelloy c22

Physical Characteristics

Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.

Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.

Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.

Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.

Chemical Properties

Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.

Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.
