Material types

You can freely use hundreds of different kinds of metal and alloy to accomplish manufacturing of fine parts. When choosing materials, please consider the features, processing performance, appearance and cost of the material.

Yukai has employed industrial analysis and material application engineer who has over 20 years of working experience. We can provide the best solution for you. We can improve precision of products and prolong service life of products by using different raw materials with ideal hardness and various surface treatment.


Yukai can treat various kinds of materials including: alloy steel, steel, stainless steel, aluminum, alloy titanium, special steel, brass, copper, plastic etc.

Alloy Steel Type: 4140, 4142, 41L40, 8620, 52100, SKD11, SKD61
Machining Characteristics: alloy steel is suitable for products with requirements on strength
Stainless Steel Type: SS303, SS304, SS316, SS416, SS430, SS440, 17-4PH etc.
Machining Characteristics: stainless steel is mainly used for products which can not rust and should be corrosion resistant. It is difficult to process stainless steel. The machining efficiency is low. The machining and customization of stainless steel parts are quite challenging. But Yukai team knows well about the unique performance of 150 kinds of stainless steel. We can adjust our production process and improve the production efficiency at the max limits, ensuring the delivery time.
Steel Type: 1008, 1018, 1045, 1137, 11L37, 11L41, 12L14, 12L15, 4130, 4140, 8620, Q235, Q345B, 20#, 45# etc.
Special steel Type: Tungsten steel, ASP23, SKH51 etc.
Machining Characteristics: SKH51high speed steel is popular in most applications because of its superior well-balanced toughness and wear resistance which is two times that of high carbon steel. SKH51 high speed steel is suitable to be made to tools with high wear resistance and hardness because it can keep the hardness of 64 HRC under 600℃ without deformation.
Alloy Titanium Type: Ti6AI-40, Ti6AI-40 ELI
Machining Characteristics: compared with other materials, alloy titanium features high strength and weight. It also features good malleability, salt tolerance and water corrosion resistance. It is the ideal selection of many industries and applications.
Aluminum Type: AL6061, Al6063, AL6082, AL7075, AL2011, AL2024, AL6051
Machining Characteristics: among the materials to be machined, aluminum parts are the most economical. The CNC machining and milling time of aluminum parts are shorter than that of the other metals. Because of the protective layer on the surface after being exposed to the air, the strength, corrosion resistance anti-rust property of the product are improved. Besides, the aluminum parts feature chemical resistance, malleability and high strength. For these advantages, Yukai focuses on being leader of CNC machining of aluminum parts.
Brass Type: C35300, C36000, HPb63, HPb62, HPb61, HPb59, H59, H58, H68, H80, H90 etc.
Machining Characteristics: compared with machining of other materials, brass turning parts are durable. It is economical. Brass machining and turning parts feature high heat tolerance and corrosion resistance. The machining and turning of brass parts are easy.
Copper Type: C11000, C14500, C17200, C17300, C17500, C12000, C36000 etc.
Machining Characteristics: copper is the known best electric conductor. Meanwhile, the cost is relatively low. Yukai team found that copper machining is a smooth and simple process. Copper also features high corrosion resistance so that the copper parts are widely welcome in electrical applications.
Plastic Type: Acetal, Delrin, Nylon, Peekm PTPE, Teflon, PVC, ABS, PC, PE, POM, PP, PEI etc.
Machining Characteristics: plastic parts are widely used in daily life and industry. Yukai team knows well about unique features of high performance and standard practical plastics. We know well about the most suitable shaft speed and feeding speed of plastic machining. Meanwhile, we adopt the special high precision cutter for plastic machining.
