Corundum

硬度高，韌性大

High hardness and toughness

適用於中高抗張強度金屬材料的磨削，如一般碳素鋼，合金鋼，可鍛鑄鐵，硬青銅等。

Applicable to high tensile strength metal grinding, such as general carbon steel, alloy steel, malleable iron and hard bronze

WA

白剛玉

Fused

硬度高於棕剛玉，磨粒易破碎，棱角鋒利，切削性能好，磨削熱量小等。

Hardness than corundum, abrasive easily broken, sharp edges and corners, good cutting, grinding heat and small.

適用於材料較硬，熱敏感性較強鋼材的磨削。如淬火鋼，高碳鋼，一般高速鋼，合金鋼等的磨削。主要用於工具，刃具，模具，齒輪，螺紋，薄壁零件等的磨削及成型磨削。

Be applied in hard, strong steel grinding heat sensitive.Such as hardened steel, high carbon steel, general high speed steel, alloy steel grinding.Used tools, cutting tools, gear, thread, thin-walled parts such as grinding and grinding

PA

鉻剛玉

Chrome-corundum

硬度與白剛玉相近，韌性則比白剛玉高，磨粒切削刃鋒利，棱角保持性好，耐用度較高。

Similar hardness and white fused alumina, white fused alumina than in the high toughness, abrasive cutting edge sharp edges and corners to keep good, high durability.

適用於淬火鋼，合金鋼刀具及工件的磨削以及量具和機表零件等的精密磨削，也適用於成型磨削。

For hardened steel, alloy steel grinding tool and the workpiece and the measuring and instrumentation components such as precision grinding, also apply to grinding

SA

單晶剛玉

Single-crystal corundum

與棕，白剛玉相比硬度高，韌性大，呈單顆粒球狀晶體，具有良好的多棱切削刃，抗破碎較強。

With brown, white fused alumina compared to high hardness, toughness, showed a single particle spherical crystal, has a good multi-row cutting edge, strong anti-crushing

適用於不銹鋼，高釩鋼速鋼等硬度高，韌性大及易變形，易燒傷工件的磨削加工。

For stainless steel, high speed steel, vanadium steel, high hardness, toughness and deformation, easy to burn the workpiece grinding.

MA

微晶剛玉

Corundum ceramics.

磨粒由微小晶體組成。韌性大，強度高，磨料自銳性好。
