Introduction to Physical Properties of marble and granite Mechanical Components

Marble Components: Capable of being processed with T-grooves, drilled holes, V-grooves, dovetail grooves, or embedded with metal sleeves in grooves/holes. These products are widely exported to countries like the U.S., Japan, and Germany, with significant demand in China’s Jiangsu, Zhejiang, Shanghai, and Guangdong regions. Customized according to customer-provided blueprints, they are crafted from premium "Jinan Green" stone through mechanical machining and manual fine grinding. Key features include a sleek black luster, precise structural composition, uniform texture, excellent stability, high strength and hardness, the ability to maintain high precision under heavy loads and normal temperatures, as well as rust resistance.

Characteristics of Marble Components

1. After long-term natural aging, marble and granite mechanical components have uniform organizational structures, extremely low linear expansion coefficients, completely eliminated internal stress, and no deformation.

2. Good rigidity, high hardness, strong wear resistance, and minimal thermal deformation.

3. Resistant to acid and corrosion, non-rusting, no need for oiling, less prone to dust adhesion, easy maintenance, and long service life.

4. No scratches, not restricted by constant temperature conditions, and can maintain measurement accuracy at room temperature.

5. Non-magnetic, smooth movement without stiction during measurement, unaffected by humidity, and stable flatness.
