Mohs hardness 6\u20137, higher than marble (3), ordinary steel, and ceramic tiles; daily tools and keys cannot scratch the surface.
Shore hardness 71\u201379, minimal wear from long-term foot traffic and friction, suitable for plazas, driveways, and kitchen countertops.<\/li>\n\n\n\n
Compressive strength: fine-grained 147\u2013284MPa, medium-grained 117\u2013147MPa, coarse-grained 78\u201398MPa, extremely strong load-bearing capacity.
Minimal elastic deformation, extremely low coefficient of thermal expansion (4.7\u20139\u00d710\u207b\u2076\/\u2103), dimensions remain almost unchanged with temperature fluctuations, making it a core material for precision CMMs and inspection platforms.
Density 2.6\u20132.8g\/cm\u00b3, high self-weight, good stability, and anti-overturning.<\/li>\n\n\n\n
Porosity 0.04%\u20132.8%, water absorption rate only 0.11%\u20130.7%, almost no water or oil seepage.
Freeze-thaw resistance: can withstand 200 repeated freeze-thaw cycles at -40\u2103 without cracking; long-term use in outdoor cold regions without cracking or crumbling.<\/li>\n\n\n\n
Does not easily crack under sudden cooling or heating at room temperature; however, continuous high temperatures above 800\u2103 will cause quartz crystal phase transformation and overall shattering, so it cannot be baked over an open flame for long periods.<\/li>\n\n\n\n
Polishing can achieve a high mirror gloss; can be processed with flamed, leather, brushed, or antique finishes; good performance in cutting, drilling, and grooving.
III. Chemical Corrosion Resistance
Extremely strong acid and alkali resistance: ordinary hydrochloric acid, sulfuric acid, strong alkalis, and acid rain do not corrode, whiten, or dissolve the surface upon long-term contact;
Only weakness: hydrofluoric acid (HF) will corrode quartz, so use with caution in chemical environments containing HF;
Weathering and oxidation resistance: does not discolor or powderize after decades of outdoor exposure; ancient buildings and stone tablets can be preserved for a thousand years.
IV. Appearance, Color, and Texture Characteristics
Color tones are determined by minerals: feldspar is whitish\/flesh-red, mica has black spots, and iron oxides appear red; common colors include sesame white, sesame gray, black gold sand, Indian red, green diamond, etc.;
Every slab has a unique texture, natural speckled crystalline texture, with no repeating patterns;
After polishing, the crystal reflection is delicate, with a heavy and premium texture.
V. Safety and Radioactivity
Natural stone contains trace amounts of uranium and thorium; Class A granite has extremely low radioactivity and is suitable for both indoor and outdoor use; Class B and C are only restricted to exterior walls; products that pass regular testing are harmless to the human body.
