5083 Tooling Plate – Machined Cast Tooling Plate
- Stable Strength: Through special casting and heat treatment processes, the strength can reach 85–90% of equivalent rolled plates.
- Dimensional Stability: Precision double-sided machining ensures flatness tolerance, suitable for high-precision tooling.
- Residual Stress Relief: Special processing results in extremely low residual stress, minimizing warping during subsequent machining or thermal cycling.
Machinability and Stability:
- Precision milled surface roughness Ra ≤ 0.4 μm to ensure dimensional accuracy.
- Stress relief and homogenization are performed during production to minimize deformation during high-speed machining.
- Isotropic grain structure ensures uniform mechanical properties in all directions.
5083 Tooling Plate – Physical and Thermal Properties
- Density: 2.66 g/cm³
- Thermal Conductivity: ≈ 117 W/(m·K) (typical value for 5000 series alloys)
- Coefficient of Thermal Expansion: ≈ 23.5 × 10⁻⁶ /°C (20–100 °C)
- Maximum Service Temperature: 65 °C; above this temperature, strength and corrosion resistance decrease.
5083 Tooling Plate – Corrosion Resistance
- 5083 exhibits excellent general corrosion resistance, seawater corrosion resistance, and resistance to industrial chemicals.
- Prolonged exposure to loads exceeding 65°C may lead to stress corrosion cracking, so the service temperature should remain within the recommended range.
- Certified by classification societies (DNV, Lloyd’s) and compliant with ASTM B928M standard, ensuring suitability for marine environments.
Corrosion Resistance:
- Resistant to seawater and industrial chemical corrosion, making it an ideal choice for marine environments (e.g., hulls, keels, and stacks).
- Performs well in low-temperature conditions without brittleness, suitable for LNG tanks and cryogenic applications.
5083 Tooling Plate – Welding and Fabrication
- 5083 maintains excellent strength after welding and can be joined using MIG, TIG, and friction stir welding, with minimal corrosion in the heat-affected zone.
- Controlling interpass temperature can reduce overaging in the heat-affected zone.
Weldability:
Good strength retention after welding; filler alloys such as 5183 or 5356 are recommended for optimal results.
