(イ) 機械的強度が高い（250Kg／mm2以上）、
(ロ) 硬度が高い（Hv＝700〜900）、
(ハ) 弾性係数が低い、
(ニ) Cr等の添加により耐食性が著しく向上す
る、
(ホ) 自由表面の光沢が良い、
などの性質を有するものであつて、これ等は電気
カミソリの外刃にとつて非常に適している性質で
ある。この理由は外刃厚を薄くする事によつて深
剃のできる刃を製作した時に、刃の強度が低下し
ないことによるものであり、また硬度が高いのは
切刃エツジの耐摩耗性が高くなり、長寿命の刃を
うることができる。耐食性が高いのは肌の分泌物

性係数が低いのは、ネツト外刃では内刃と密着し
やすく、切味のよい刃が得られる等の理由による
ものである。しかるにこのアモルフアス金属には
塑性加工が困難であるという唯一の欠点を有する
ことである。 In general, a solid amorphous metal obtained by rapidly cooling a molten metal at, for example, 10 6 °C/second (vitrifying it) is called an amorphous metal. Because it does not have a regular atomic arrangement such as High (250Kg/mm2 or more ), (B) High hardness (Hv=700-900), (C) Low elastic modulus, (D) Corrosion resistance is significantly improved by adding Cr, etc., (E) Free surface It has properties such as a good gloss and these properties are very suitable for the outer blade of an electric razor. The reason for this is that the strength of the blade does not decrease when creating a blade that can achieve a close shave by reducing the thickness of the outer blade, and the high hardness is due to the high wear resistance of the cutting edge. This allows you to obtain a blade with a long life. High corrosion resistance means that it can withstand corrosion caused by skin secretions or washing with water. The reason why the elastic modulus is low is that the net outer cutter easily comes into close contact with the inner cutter, resulting in a blade with good cutting quality. However, the only drawback of this amorphous metal is that plastic working is difficult.
従来カミソリ外刃にはシンク加工と云つて、刃
穴の縁部を内刃側に盛り立て、その面を研削して
仕上げて製造していた。このようにすることによ
つて、
(a) 内刃と外刃との接触面積が減つて負荷が軽く
なる、
(b) 外刃の切刃エツジが鋭角になる、
(c) 外刃の肌に対する当りがなめらかになる、
という効果が得られる。 Conventionally, the outer blade of a razor was manufactured using a sink process, in which the edge of the blade hole was raised on the inner blade side and the surface was ground and finished. By doing this, (a) the contact area between the inner cutter and the outer cutter is reduced, which reduces the load, (b) the cutting edge of the outer cutter becomes acute, and (c) the skin of the outer cutter becomes sharper. This has the effect of making the impact smoother.

Examples include CO 75 Si 15 B 10 , Fe 80 P 13 C 7 , Fe 72 Cr 8 P 13 C 7 and the like. For example, CO 75 Si 15 B 10 has a hardness of 910Hv and a tensile strength of 306Kg/mm 2 , Fe 80 P 13 C 7 has a hardness of 760Hv and a tensile strength of 310Kg/mm 2 , and Fe 72 Cr 8 P 13 C 7 has a hardness of 850Hv.
