Mold-specific aluminum is a special industrial aluminum material different from civilian aluminum, mainly used for auxiliary structures, mould frames and supporting parts of low-pressure moulds, extrusion moulds and stamping moulds. Many users confuse ordinary civilian aluminum with industrial mould aluminum, resulting in insufficient structural stability and low precision of mould accessories. Xinfeng Machinery classifies industrial mould aluminum materials in detail to provide accurate selection reference for mould customization and procurement.
7075 aviation aluminum is the highest-grade mould aluminum material, belonging to high-hardness and high-precision industrial aluminum. After heat treatment and stress relief, its hardness reaches HB150, with extremely low deformation rate and ultra-high dimensional stability. It is widely used for precision positioning parts, guide rail structures and high-precision mould auxiliary components of low-pressure die casting moulds and differential pressure moulds. In high-precision mould processing, 7075 aluminum has a stability rate of 99%, far higher than other aluminum grades.
6061 and 6063 aluminum are conventional universal mould aluminum materials. 6061 aluminum has balanced performance, suitable for most conventional mould base and auxiliary structural parts, with moderate price and stable processing performance. 6063 aluminum has low hardness and poor precision stability, only suitable for simple non-precision mould brackets and fixed structures, and cannot be used for precision matching parts of high-end moulds. The processing precision of 6063 aluminum is 15% lower than 6061, with higher long-term deformation risk.
Special-scenario mould aluminum includes 5052 anti-corrosion aluminum and 2024 high-strength aluminum. 5052 aluminum has excellent oxidation and corrosion resistance, 45% higher than ordinary aluminum, suitable for mould accessories in humid and corrosive casting workshops. 2024 aluminum has outstanding tensile strength and impact resistance, used for heavy-load supporting structures of large extrusion moulds and stamping moulds to bear mechanical load pressure.
Cast aluminum is a low-cost mould auxiliary material, with procurement cost 35% lower than forged aluminum. Due to internal loose structure and low precision, it is only suitable for low-precision and low-batch simple mould frame production, and cannot adapt to high-precision and high-cycle industrial mould production scenarios.
