CAC406, a type of tin bronze alloy, is highly esteemed for its outstanding combination of mechanical properties and corrosion resistance. This makes it a top - pick for numerous industrial applications. This article offers a thorough examination of the CAC406 tin bronze tube, covering its chemical composition, mechanical properties, heat treatment conditions, low - temperature impact testing results, available size range, primary applications, and relevant supply cases from TJC Steel Group.

Chemical Composition

CAC406 mainly consists of copper, with substantial amounts of tin added. Tin is the key element contributing to its remarkable strength and corrosion resistance. The typical chemical composition of CAC406 is as follows:

· Copper (Cu): 88.0 - 91.0%

· Tin (Sn): 8.0 - 10.0%

· Zinc (Zn): ≤ 1.0%

· Lead (Pb): ≤ 0.2%

· Iron (Fe): ≤ 0.1%

· Residuals: ≤ 0.7%

Mechanical Properties

CAC406 showcases a well - balanced set of mechanical properties, rendering it suitable for challenging applications. The key mechanical properties are:

· Tensile Strength: 415 MPa (60 ksi)

· Yield Strength: 170 MPa (25 ksi)

· Elongation: 40%

· Hardness: 110 HB (Brinell Hardness)

Heat Treatment Conditions

CAC406 can undergo heat treatment to optimize its mechanical properties. The standard heat treatment process involves solution annealing at 700°C (1292°F), followed by water quenching. Subsequently, it is aged at 480°C (896°F) for 4 hours, and then air - cooled to room temperature.

Low - Temperature Impact Testing

CAC406 exhibits excellent impact resistance even at low temperatures, a crucial characteristic for applications in cold environments. Typically, the alloy meets the Charpy V - notch impact energy requirements of 40 J (30 ft - lb) at - 40°C.
