Material Specifications: ZHHIMG Black Granite vs. Marble
Material substitution remains a critical risk in the precision manufacturing supply chain. Some manufacturers reduce costs by substituting genuine precision granite with standard marble. ZHHIMG strictly prohibits this practice, adhering to our operational standard: No cheating, No concealment, No misleading.
Physical Properties and Density
Precision components require absolute dimensional stability. ZHHIMG Black Granite has a verified density of ≈3100kg/m3. This high density provides superior vibration damping and physical stability compared to standard marble. These properties are critical for granite air bearings and measuring rulers, ensuring long-term accuracy and resistance to environmental variance.

Material Traceability
ZHHIMG maintains a dedicated 20,000m2 raw stone yard to ensure complete material traceability. Our quality policy dictates that precision manufacturing cannot be compromised. All ZHHIMG Precision Granite components are manufactured exclusively from verified, high-density black granite, meeting global metrology standards.
