At present, there are more than 200 kinds of 3D printing materials. From the perspective of direct digital manufacturing, more than 200 materials are still minimal because there are many products in reality, and the production materials and their combinations are also complicated.
Not all materials can be precision machined in precision parts processing. Some materials have too much hardness and exceed the hardness of the machined parts, which may break the parts, so these materials are not suitable for precision machining.
The strength and hardness of steel are one of its most sought-after properties. They make steel suitable for construction and transportation applications because it can be used for a long time under heavy and repeated loads. Some steel alloys, the stainless steel varieties, are resistant to corrosion, making them the best choice for parts operating in extreme environments.
The first digit indicates the type of aluminum alloy, consisting of 1-9, and different numbers indicate different alloy compositions.
The second number indicates the modification of the alloy composition, 0 indicates the original composition, 1 indicates the first modification, 2 indicates the second modification, and so on, indicating the difference in the content of different alloy elements. For example, 7075 represents the original aluminum-zinc alloy, 7175 and 7475 represent the aluminum-zinc modified alloy, and 7175 and 7475 are the modified grades of 7075.
The 3rd and 4th digits denote a specific alloy within that family of alloys. The values of these numbers have no special meaning.
The materials for CNC machining are mainly divided into 3 categories, namely metal, non-ferrous gold and non-metallic materials. This article introduces 18 common material options.
Common materials for industrial robot parts can be divided into metal, non-metal, and composite materials, according to the function classification, structural materials, coating materials, control materials, etc. Now let us introduce the common materials one by one. Enjoy reading!
