Low aluminum low calcium FeSi72% powder

72 Silicon Iron Powder Overview

72 Silicon Iron Powder (chemical formula Fesi72) is a type of iron alloy powder with a silicon content of approximately 72%. It is widely used in steel smelting, casting, and metal magnesium production, etc. Its main components are silicon (Si) at about 72%, iron (Fe) at 25%-28%, and also contains trace amounts of carbon (C), aluminum (Al), calcium (Ca), and other elements.

Key features:

High silicon content: Silicon content ≥ 72%, with significant effects in deoxidation and silicon addition.

Grain size adjustable: Common specifications include 0-1mm, 1-3mm, 200 mesh, etc.

Low impurities: High-quality 72 silicon iron powder requires low aluminum (Al ≤ 1.5%) and low calcium (Ca ≤ 1%).

Prone to oxidation: Requires moisture-proof packaging to prevent the risk of dust explosion.

2. Product Classification

By granularity: Fine powder (0 - 1mm), Medium particle (1 - 5mm), Blocky (10 - 50mm).

By application: steel deoxidizer, casting agglomerator, magnesium metal reducing agent, etc.
