CAC406, a remarkable tin bronze alloy, is celebrated for its exceptional blend of mechanical prowess, corrosion resistance, and wear resistance. This alloy finds extensive application across diverse industries where top - notch performance and durability are non - negotiable. The following provides an in - depth exploration of the CAC406 tin bronze plate, encompassing its chemical makeup, mechanical characteristics, heat treatment parameters, low - temperature impact test results, available dimensions, primary application areas, and supply cases from TJC Steel Group.

Chemical Composition

The unique properties of CAC406 stem from its carefully balanced chemical composition:

· Copper (Cu): Constitutes 88.0 - 91.0% of the alloy. Copper provides the base structure and contributes to the alloy's electrical conductivity and ductility.

· Tin (Sn): Ranging from 8.0 - 10.0%, tin enhances the alloy's hardness, strength, and corrosion resistance. It forms hard intermetallic compounds with copper, improving the overall mechanical properties.

· Zinc (Zn): Present at ≤ 1.0%, zinc can slightly modify the alloy's properties, such as improving fluidity during casting in some cases.

· Lead (Pb): With a maximum content of ≤ 0.25%, lead can enhance machinability, although excessive amounts can reduce the alloy's strength.

· Iron (Fe): At ≤ 0.10%, iron can form hard particles in the alloy, potentially increasing wear resistance if controlled.

· Aluminum (Al): Limited to ≤ 0.005%, aluminum can have an impact on the alloy's oxidation resistance and microstructure.

· Silicon (Si): ≤ 0.005% of silicon may influence the alloy's fluidity during melting and casting.

· Phosphorus (P): At ≤ 0.01%, phosphorus is often added to deoxidize the alloy and can improve its strength and wear resistance.

Mechanical Properties

CAC406 showcases a set of mechanical properties that render it suitable for exacting applications:

· Tensile Strength: Reaching 415 MPa (60 ksi), this indicates the alloy's ability to withstand pulling forces without breaking. It is crucial for applications where the material is subjected to tension, such as in structural components.

· Yield Strength: Standing at 170 MPa (25 ksi), the yield strength defines the stress at which the alloy begins to deform plastically. It helps in determining the maximum load the material can bear elastically.

· Elongation: With an elongation of 35%, CAC406 exhibits good ductility, meaning it can be stretched or deformed significantly before fracture. This property is essential for processes like forming and shaping.

· Hardness: Measuring 100 HB (Brinell Hardness), the alloy has a moderate hardness, which contributes to its wear - resistant nature.

Heat Treatment Conditions

Heat treatment is a key process to optimize the mechanical properties of CAC406. The typical heat treatment regimen involves solution annealing at 540°C (1000°F) for 1 hour. This step dissolves alloying elements into the copper matrix, homogenizing the microstructure. Subsequently, water quenching rapidly cools the alloy, "trapping" the dissolved elements in a supersaturated state. Finally, aging at 370°C (700°F) for 4 hours allows the precipitation of fine - scale particles, which further strengthen the alloy.

Low - Temperature Impact Testing

CAC406 demonstrates outstanding performance in low - temperature impact testing. Even at sub - zero temperatures, it retains its ductility and toughness. This makes it an ideal choice for applications in cold environments, where materials need to withstand sudden impacts without brittle fracture.
