Thin Aluminum Plate

1060-O  

• Provide good heat insulation. The additional knurling and Embossing process will increased surface area of the flat aluminum plate so as to improve heat diffuse reflection effect, and achieve a better insulation effect.

• Easy Molding. It’s thin and soft, easy to be formed for a relatively complex structure.
• Light weight. Easy to achieve component and assembly weight limitation.
• However, the strength is poor and easy to deform. The sandwich structure combined from high temperature resistant fiber fillers commonly used for non-exterior parts requesting very high heat insulation performance.

Thick aluminum plate  

1060-O  

Thick aluminum plate has good heat insulation, and strength better than thin aluminum plate, has light weight and easy to form shape. Anodized surface treatment will provide much better performance. The cost is relative high. Recommend to use for light vehicles exterior parts requesting very high heat insulation performance.

Heat-resistant Aluminum Plate for deep drawing

• The mechanical properties are close to stainless steel, but heat insulation performance is poorer than aluminum plate. The surface is aluminized for heat insulation and corrosion protection.
• Good strength, but poor molding ability. Complex structure is difficult to achieve, it has low cost but heavy weight, mostly used for parts that requesting low temperature insulation and high strength structure, and models that are not strict about body weight and component weight.

Stainless steel

Has very good strength, but not easy to achieve complex forming, mostly used for bending structural parts.

Has excellent corrosion resistance but relatively high price.

Commonly used in normal heat insulation but very high strength structure. And used for fine exterior parts which need polishing, wire drawing and other surface treatments.

Heat Shields Design

Heat Insulation Performance Summary

Aluminized Steel Heat Shield

The mechanical properties are close to stainless steel plate. The surface is aluminized for heat insulation and corrosion protection. Provide very good structural strength and low cost, but the molding ability is general. It’s heavy and mostly used for parts requesting low temperature insulation and high strength structure.

Sandwich Heat Shields ( Aluminized Steel Plate + Heat Insulation Filler )

Commonly used for exhaust manifold heat shields. But when the temperature exceeds 600 °C, ablation problem occurs in the aerobic environment, which will lead bad affect the heat insulation and the high temperature resistance becomes worse.

Sandwich Heat Shields

(Thin Aluminum Plate + Heat Insulation Fiber/Ceramic Fiberboard )  

Aluminum plate itself has good heat insulation performance, but when the temperature of heat insulation fiber board exceeds 600 °C, ablation problem occurs in the aerobic environment, which will lead bad affect the heat insulation and the high temperature resistance becomes worse. Ceramic fiber board can withstand temperatures up to 1000 °C. But the overall structural strength is poor and easy to deform.

Embossed Aluminum Plate + Reinforced Mesh Washer/ Damping Washer

(single layer, double layer)

Good heat insulation effect, light weight. When mesh washers or damping washers applied, the heat shields can be directly installed on the heat surface of 850 °C.

Has a high molding ability and vibration resistance, good noise attenuation performance. This type of heat insulation structure is not easy to deform and crack.
