铁砂又名配重砂，由铁丸经热处理后破碎而成。硬度高、棱角锋利，其破碎后形成的尖锐的边缘使其具有高速喷刻蚀和刮削特性，特别用于对刻蚀和刮削要求较高的金属表面处理，也用于室外喷砂作业的表面处理工程。铁砂硬度适中、韧性强、抗冲击、可连续几次反复使用、寿命长、反弹性好、附着力强、清理速度快、砂耗低、不破碎、清理工件亮度大、效果好。

      铁砂包括铁砂丸、喷涂铁砂、雾化铁砂、配重铁砂。表面粗糙度达25--100um，从而增加了金属表面的接触面，提高了涂抹的表面附着力，对细化金属表面强化金属结构，具有很好的经济效益，是目前国内外 先进、 理想的清理喷抛、除锈和强化的 质材料。

Also known as the iron ore with heavy, by iron pills after heat treatment and crushing. It has high hardness, sharp edges, and its sharp edge formed by crushing, which has high speed spray etching and scraping characteristics, especially for metal surface treatment with high requirements for etching and scraping, and also for surface treatment engineering of outdoor sandblasting. Iron moderate hardness, strong toughness, impact resistance, can use repeatedly for several times, long service life, good elasticity, strong adhesion, cleaning speed, sand consumption is low, not broken, high brightness, good effect of cleaning work.
Iron, iron ore, iron ore pellets including spraying atomized iron ore, iron ore weight. The surface roughness of 25--100um, thereby increasing the contact surface of the metal surface, improve the coated surface adhesion, to refine the metal surface strengthening metal structure, and has good economic benefit, is the current domestic and foreign advanced, ideal cleaning spray polishing, rust removal and reinforcement material. .
