The researcher of the lab has developed A Mosi to plant change boron than cubic nitrogen (the stuff with CBN) even a bit more expensive hardness. The AlMgB14 coating that pursues deposit on steel matrix (the layer with darker color of brim of matrix of steel of the edge in the graph) a few days ago, diamond remains the foregone hardness is highest material on the earth. But, the researcher of A Mosi lab has developed subordinate of American energy department to plant change boron than cubic nitrogen (the stuff with CBN) even a bit more expensive hardness. A Mosi lab alleges them with its lab of his a few scientific research, university and company cooperate, develop a kind of applicable the coating with the tall hardness at cutting cutting tool and wear-resisting spare parts, tall tenacity, slick surface. For example, group of this scientific research with tool manufacturer greenery (Greenleaf) company cooperation is deposit on its cutting tool coating of a kind of macrobian life chafes with reducing and cutting force, reduce cutting to machine needs specific power consumption thereby. The researcher of the lab passes A Mosi to be mixed in aluminous, magnesium boracic alloy (join in AlMgB14) a few silicon and other additive development gave this kind of data. This kind of compound is not kind of new material, but its chemistry character has not consider completely to be clear about. This kind of alias is " BAM " (the material of Boron-Aluminum-Magnesium) showed extremely tall hardness -- 46GPa(is equivalent to 6.

7 × 106psi) , compare with this photograph, the hardness of CBN is equivalent to for 45GPa(6.

5 × 106psi) , the hardness of diamond is equivalent to for 70 ～ 100GPa([10.

2 ～ 14.

5] × 106psi) . From the point of the structure of the main ingredient unit of BAM, it makes a kind of solid material unlikelily it seems that. The main ingredient of diamond has 8 carbon atom in unit, arrange mix very simply the structure of high semmetry. And 64 atom are shared in the main ingredient unit of BAM, any experts won't think the material that has structure of this kind of crystal will be very solid. But in fact, BAM is really adamant! The researcher explanation of A Mosi lab says, pass displacement other element (the) that be like silicon, the chemical structure with this kind of complex compound makes raise its hardness to become a possibility. Researcher joins silicon in material, changed its successfully to combine a condition. Make material hardness rises greatly. Hardness is not the performance advantage with this kind of unique material, wearability, tenacity and hot conductibility also are the main factor of the usability in affecting this kind of material to be machined in cutting. BAM had obtained the sale license of company of New Tedl Ceramics, this company can provide AlMgB14 series data. Because AlMgB14 material has better figuration capacity. Production photograph contrast is easier, production cost is inferior also, because this is in,exceed hard data stronger competition ability is had on the market. CNC Milling CNC Machining
