The adaptability of metals to various processing methods is called process performance, and there are four main aspects:
(1) Machining performance: Reflects the difficulty of cutting metal materials with cutting tools (such as turning, milling, planing, grinding, etc.).
(2) Forgeability: Reflects the difficulty of forming metal materials during pressure processing, such as the plasticity of a material heated to a certain temperature (expressed as the degree of plastic deformation resistance), allowing the temperature range of hot pressure processing, Thermal expansion and contraction characteristics and limits of critical deformation related to microstructure and mechanical properties, fluidity of metal during thermal deformation, thermal conductivity, and the like.
(3) Castability: Reflecting the difficulty of melting and casting a metal material into a casting, showing fluidity, aspiration, oxidation, melting point, uniformity, compactness, and cold shrinkage of the microstructure of the casting. Wait.
(4) Solderability: Reflecting the rapid heating of the metal material in the local part, so that the bonding part is rapidly melted or semi-melted (requires pressure), so that the bonding parts are firmly bonded together to become a whole degree of difficulty, which is expressed as melting point and melting. The gettering property, oxidizing property, thermal conductivity, thermal expansion and contraction characteristics, plasticity, and the correlation with the microstructure of the joint portion and the nearby material, and the influence on the mechanical properties.
For Functional Monomer series, we can supply many kinds of Health Care Intermediates with good quality, such as Allyl Acrylate , 2,2,2-Trifluoroethyl Acrylate, 2,2,3,3-Tetrafluoropropyl Methacrylate, Isobornyl Acrylate, Isobornyl Methacrylate.
We have our own production factories and lab. We can develop new product according to customer`s require, because we cooperate with several university, please believe that we have research advantage. Our factory is in chemical industry park, gets produce license from government, can supply product steadily.
