Grade Selection Guide

Grade	Applications
KU20	Sub-fine grain size, processing by medium speed, good general performance, drill bits and end mills are recommended, suitable for cutting Ordinary alloy steel, aluminum alloy, heat resistant alloy, cast iron, etc.
KR10Z	Ultra-fine grain size, excellent heat resistance, suitable for high-speed milling and drilling, especially suit for making overall drill bits. Suitable to process alloy steel, heat-resistant alloy, cast iron, non-ferrous metals, stainless steel and other materials.
KU25	Ultra-fine grain size, with good wear resistant and toughness, especially suitable for finishing and processing alloy steel, aluminum alloy, titanium alloy etc. Suitable for making end mills and reamer.
KU409	Ultra-fine grain size, Suitable for processing hardened hard steel, aluminum alloy, CFRP, high wear resistant material stainless steel, composite graphite, PCB, plastic.
KU10	Ultra-fine grain size, with good wear resistant, higher wear resistant end mills, engraving tool and high mirror polished cutting tool are recommended, suitable for processing Aluminum-magnesium alloy, composite sheet, PCB, plastic, CFRP etc.
KU209	Nano grain size, with high wear resistance and toughness, suitable for finishing of hardened steel, high-precision and high-mirror processing of graphite, plastic, CFRP, stainless steel and aluminum alloy. Suitable for making 0.3-0.5mm drills.
KU30	Sub-fine grain size, with good wear resistant and toughness, suitable for making punching of mould, anti-vibration boring bar and machining low-hardness material with deep cutting tools.

Definition of Physical Properties

Hardness:

The hardness of a material is defined as the ability to fight against the hard-pressed into surface of the object, mainly using measurements of Rockwell and Vickers.  As the principles of the Vickers and Rockwell tests are different, care must be taken when converting from one system to the other.
