CHROMIUM PLATING

BRILLIANT LUSTRE WILL NOT PEEL OR BUST The advantages of chromium plate as applied to motor cars are obvious. Now, the radiator shell, headlight rims, radiator ornament, etc., can never tarnish and will hold their brilliant lustre indefinitely- No more laborious polishing is required- The danger of scratching formerly so prevalent is now entirely obviated.

Every motorist living along the seacoast has had experience with radiators and salt air—rather discouraging experience, too, it might be added. Now, however, motorists along the seaboard may have their brightwork just as well as their inland brethren. For chromium scoffs at salt air.

Furthermore, chromium will not peel and is so heat resisting that the radiator core itself could melt away and its plating would never be disturbed.

A few of its uses in industrial and professional life may serve to give an accurate picture of its qualities. In factories where there is need for much filing of exceedingly hard metals, chromium has been introduced as a plating for files. It has been found that a plating of this wonder metal no thicker than one-thousandth of an inch prolongs the life of a file three or four times.

Surgical instruments which in the name of humanity must possess the sharpest possible edge are chromiumplated, which not only permits the keenest kind of cutting edge but is also rust-proof and hence far more sanitary than plain steel. The United States Bureau of Standards, assigning the diamond with the arbitrary hardness value of ten, rates chromium at nine and its nearest compctitior, steclite, at eight. Like the diamond, anything coated with chromium will scratch glass and also the hardest steel place. Much brass work on ships now receives chromium plating to render it impervious to salt spray.
