Rubber to Metal Bonded Product
Rubber materials, as elastomeric polymer materials, are widely used in functional components such as sealing and vibration damping.
Metal materials, typically offer superior rigidity compared to rubber.
By combining these two materials, it is possible to compensate for the limitations of each, enabling the resulting composite to simultaneously meet the requirements for abrasion resistance, chemical resistance, and sealing performance in diverse applications.

Material Property
Metal components are usually manufactured through processes such as stamping and die casting, and for small batch requirements, they can also be processed through machining.Common metal materials include carbon steel (such as DC01), stainless steel (such as SUS430), and aluminum magnesium alloy.
Metal Material Properties Comparison
| Property | Carbon Steel (DC01) | Stainless Steel (SUS430) | Al-Mg Alloy (e.g., 5083) |
|---|---|---|---|
| Density (g/cm³) | 7.85 | 7.70–7.80 | 2.66–2.68 |
| Tensile Strength (MPa) | 270–420 (annealed) | 450–600 (annealed) | 270–330 (rolled) |
| Yield Strength (MPa) | 140–280 | 250–350 | 110–230 |
| Elastic Modulus (GPa) | 190–210 | 200–220 | 68–70 |
| Elongation (%) | 28–40 | 20–25 | 10–25 |
| Thermal Conductivity (W/m·K) | 50–60 | 25–30 | 125–140 |
| Corrosion Resistance | Low (requires surface treatment) | Moderate (resists atmospheric/weak acids) | High (resists atmospheric/seawater corrosion) |
| Typical Applications | Stamped parts, automotive panels | Household appliances, architectural trim | Shipbuilding, aerospace structures |
Working Temperature Range
Metal have wider temperature range than rubber material. So rubber working temperature need to be mainly considered.
Chemical Resistance
The following is a preliminary classification of rubber’s oil resistance, chemical resistance, and temperature resistance, which can help us choose suitable rubber materials in the design phrase.
