Material FAQs regarding Thermal Performance of Materials

Required Property	Applications & Problems	Commonly Used Materials	Recommended Materials
High Temperature Resistance	・The part used under high temperature environment requires frequent replacement due to its short service life, resulting in high cost and downtime. ・The part used at high temperature warps and distorts while in use, and these thermal deformations cause decreases in the dimensional accuracy of final products it produces.	Heat-Resistant Resin/Plastic Aluminum Alloy Steel Stainless Steel	Fused Silica Glass Borosilicate Glass Alumina Zirconia Silicon Nitride Molybdenum / Molybdenum Alloy Tungsten / Tungsten Alloy
Low Thermal Expansion	・Due to its low dimensional stability, the part expands at high temperatures, causing problems in dimensional accuracy and repeatability of the final products it produces. ・A material with low thermal expansion is needed to make a part which can maintain its performance and dimensional stability without being affected by constant changes in temperature.	Aluminum Alloy Steel Stainless Steel	Alumina Aluminum Nitride SiC based MMC Molybdenum Tungsten
High Thermal Conductivity	・A material with high thermal conductivity is required for use in fast heat removal & high temperature applications. ・Due to its low thermal conductivity at high temperatures, the critical parts for thermo-compression bonding cannot conduct sufficient heat which results in low productivity.	Stainless Steel Heat-Resistant Alloys Ceramics	Molybdenum Tungsten Aluminum Nitride Silicon Carbide SiC based MMC
High Thermal Conductivity	・It is very hard to find a material which meets all of the requirements: high temperature resistance, good thermal conductivity and excellent electrical insulation property.		Aluminum Nitride
High Thermal Shock Resistance	・The uses of low thermal shock resistant materials prevents manufacturers from improving their productivity which can be achieved by rapid heating and cooling. For example, if the mold material is not thermal shock resistant enough, rapid changes in temperature will cause distortion and cracking in molds.	Aluminum Alloy Steel Stainless Steel Ceramics	Silicon Nitride Aluminum Nitride Alumina Molybdenum Tungsten.
Low Thermal Conductivity	・The part operated at high temperatures loses heat too quickly because of its thermal conductivity. This heat loss by conduction causes variations in quality of the products. A material which can both retain heat longer and withstand high temperature is needed to replace with current material to stabilize quality.	Ceramics	Zirconia Machinable Ceramics Fused Silica Glass Borosilicate Glass
High Hardness Wear Resistance Scratch Resistance	・Rapid wear causes a part to lose its dimensional accuracy, resulting in frequent replacement of the part. ・High scratch-resistance is required.	Hardened Steel Conventional Metal(non-refractory)	Alumina Zirconia Silicon Carbide Silicon Nitride Tungsten Carbide
High Hardness Wear Resistance Scratch Resistance	・The optical component cannot stay transparent due to the damaged surface caused by scratches and abrasion during use. An extremely hard, optical material is needed to produce high-scratch resistant optical components.	Acrylic Glass	Fused Silica Glass Sapphire
High Fracture Toughness Resistance to Chipping, Cracking and Breaking	・Alumina is a popular material for precision machined parts. However, it is brittle and susceptible to breaking, chipping or cracking due to impact. A material with higher fracture toughness should be considered as an alternative material.	Alumina	Zirconia Silicon Nitride
Electrical Insulation Properties at High Temperature	・A material ideal for high temperature electrical insulation applications is needed as parts require higher heat resistance than heat-resistant resins.	Heat-Resistant Resin/Plastic	Alumina Machinable Ceramics Biron Nitride
High Electrical Conductivity at High Temperature	・An electrical conductive material with much higher temperature resistant than conventional metals is needed as they cannot withstand the intense heat.	Copper Other Conventional Metal(non-refractory)	Molybdenum Tungsten
High Density	・A high density material which enables the part to maintain its weight while reducing its size is required to improve the compactness of the product.	Conventional Metal(non-refractory)	Tungsten Tungsten Alloy
Corrosion Resistance Oxidation Resistance Alkali Resistance	・The part rusts quickly due to its constant exposure to air and water. Replacing the metallic material with a　material which can resist oxidizers is essential to end the rust problem. ・To prolong the service life of a part, it is crucial to find a material which can be used in harsh and corrosive environments that metals cannot survive.	Conventional Metal(non-refractory)	Fused Silica Glass Alumina Zirconia (Zirconium Oxide)
Cost	・Cost reduction of ceramic parts with fine features and complex shapes is needed. ・High precision and complex parts in engineering ceramics are too expensive to meet cost requirements.	Alumina Aluminum Nitride Silicon Nitride Silicon Carbide	Machinable Ceramics
