Aluminium is prized for its low density, contributing significantly to vehicle weight reduction—improving fuel economy and lowering emissions. Despite being lightweight, it offers good strength-to-weight ratio and excellent thermal conductivity, making it ideal for heat dissipation in heater systems and engine components.
Unlike iron, aluminium naturally forms a protective oxide layer, rendering it highly resistant to rust and corrosion—even in wet or salty environments. Its ductility allows for complex shaping through casting, extrusion, or stamping, enabling innovative designs in both functional and aesthetic parts. However, care must be taken during welding or joining due to differences in thermal expansion compared to steel.
Stainless Steel
Primary Applications: Exhaust systems, diesel heater housings, fasteners, and high-temperature piping.
Stainless steel combines the strength of carbon steel with superior corrosion resistance, thanks to its chromium content (typically 10.5% or higher). This makes it an optimal choice for components exposed to moisture, road salts, and high-temperature environments—such as exhaust manifolds and areas surrounding the combustion chamber.
It maintains structural integrity at elevated temperatures and resists oxidation and scaling, ensuring longevity in demanding applications. Additionally, stainless steel is a good conductor of heat, facilitating efficient thermal transfer in heating systems. Grades like 304 and 316 are commonly used depending on the level of chemical and thermal exposure required.
Copper
Primary Applications: Engine warmers, oil pans, heat exchangers, electrical wiring, and brazed joints.
Copper is unmatched in thermal and electrical conductivity, making it essential in components where rapid heat transfer or current flow is critical. In diesel heaters and engine pre-warming systems, copper tubing and plates efficiently distribute heat throughout the engine block.
It is naturally corrosion-resistant, especially in non-acidic environments, and forms a protective patina over time. Another major advantage is its recyclability—copper can be reused indefinitely without degradation in quality, supporting sustainable manufacturing practices. However, its high density contributes to added weight, and its cost is significantly higher than alternatives like aluminum or steel, limiting its use to specialized applications.
