High Density Calcium Silicate Board
1020 kg/m³ · Kelas Aluminium Cair

Pengenalan Produk

This is the molten aluminum contact grade high density calcium silicate board, specifically engineered for direct contact with molten aluminum in smelting, casting and transfer operations.

With a density of 1020 kg/m³, compressive strength of ≥17 MPa and flexural strength of ≥8.5 MPa, this product provides exceptional mechanical performance under the extreme conditions of aluminum processing.

The molten aluminum grade features superior resistance to aluminum penetration, minimal thermal shrinkage (≤0.16% at 850°C), and excellent long-term durability for trough linings, launder systems and holding furnace insulation.

Ukuran Standar: 1230 × 1230 mm, thickness 6–160 mm; 1250 × 2500 mm, thickness 10–80 mm; 1200 × 600 mm, thickness 10–160 mm (custom sizes and shaped products available)
