Common Features

1. High-Temperature Resistance: All three materials exhibit stable performance in high-temperature environments and are commonly utilized as high-temperature materials in the low-pressure casting process.

2. Corrosion Resistance: All three materials have good corrosion resistance to molten metals and can be used for a long time in the molten metal environment without being corroded.

3. Mechanical Strength: All three materials have high mechanical strength and can withstand the mechanical stress and pressure generated during the low-pressure casting process.

4. Thermal Shock Stability: All three materials have certain thermal shock stability and can withstand rapid temperature changes without breaking or deforming.

5. Application Fields: All three materials are widely used in the low-pressure casting industry for the transport and control of molten metals.

Differences in Si3N4 Riser Tube Features

• High hardness and strength: Silicon nitride has excellent mechanical strength and hardness.

• Low coefficient of thermal expansion: Low coefficient of thermal expansion, good thermal shock stability.

• Fragility: Relatively brittle

• High cost: High production cost

Differences in Aluminium Titanate Ceramic Stalk Tube Features

• Very low coefficient of thermal expansion: exhibits an exceptionally low coefficient of thermal expansion and outstanding thermal shock stability.

• Corrosion resistance to aluminum liquid: is particularly well-suited for casting aluminum and its alloys due to its corrosion resistance.

• Moderate wear resistance: demonstrates moderate wear resistance but is susceptible to wear over time.

• High brittleness: displays relatively high brittleness and is prone to cracking under mechanical stress.

Differences in Si3N4 Bond SiC (NSIC) Ceramic Stalk Tube Features

• Excellent overall performance: Combines the advantages of Si3N4 and SiC, with high strength, high hardness, and good wear resistance.

• High temperature and corrosion resistance: Demonstrates stable operation at elevated temperatures and exhibits excellent resistance to various corrosive molten liquids.

• Thermal shock stability: With a low coefficient of thermal expansion,

• Wear resistance: The addition of silicon carbide has significantly enhanced its wear resistance

The suitable material of riser and stalk tube material can be selected based on varying application requirements and working.
