Scott Martin Forum Master Posts: 11520 Registered: Apr 93	posted 04-12-2015 12:08 PM I just bumped into something I am not familiar with, it is called *Aluminum Silver. Has anyone experience with Aluminum Silver (seen product or used it)? quote: Henley's Twentieth Century Formulas, Recipes And Processes Aluminum Silver.* Aluminum and silver form beautiful white alloys which are considerably harder than pure aluminum, and take a very high polish. They have the advantage over copper alloys of being unchanged by exposure to the air, and of retaining their white color. The properties of aluminum and silver alloys vary considerably according to the percentage of aluminum. I. An alloy of 100 parts of aluminum and 5 parts of silver is very similar to pure aluminum, but is harder and takes a finer polish. II. One hundred and sixty-nine parts of aluminum and 5 of silver make an elastic alloy, recommended for watch springs and dessert knives. III. An alloy of equal parts of silver and aluminum is as hard as bronze. IV. Five parts of aluminum and 1 part of silver make an alloy that is easily worked. V. Also aluminum, 3 parts, and silver, 1 part. VI. Tiers -Argent. This alloy is prepared chiefly in Paris, and used for the manufacture of various utensils. As indicated by its name (one-third silver), it consists of 33.33 parts of silver and 66.66 parts of aluminum. Its advantages over silver consist in its lower price and greater hardness; it can also be stamped and engraved more easily than the alloys of copper and silver. VII. This is a hard alloy which has been found very useful for the operating levers of certain machines, such as the spacing lever of a typewriter. The metal now generally used for this purpose by the various typewriter companies is "aluminum silver," or "silver metal." The proportions are given as follows: Copper 57.00 Nickel 20.00 Zinc 20.00 Aluminum 3.00 This alloy when used on typewriting machines is nickel-plated for the sake of the first appearance, but so far as corrosion is concerned, nickeling is unnecessary. The alloy is stiff and strong and cannot be bent to any extent without breaking, especially if the percentage of aluminum is increased to 3.5 per cent; it casts free from pinholes and blow holes; the liquid metal completely fills the mold, giving sharp, clean castings, true to pattern; its cost is not greater than brass; its color is silver white, and its hardness makes it susceptible to a high polish.

Polly Posts: 1970 Registered: Nov 2004	posted 04-12-2015 12:19 PM Hm…very interesting! I have a number of combs and hair ornaments from the art nouveau and art deco periods that appear to be made of aluminum. Unlike aluminum items today, they're hand carved rather than mass-produced by casting. I always assumed that was because the world hadn't yet figured out how to handle aluminum the way we do now, but I wonder whether some of them could be made from an aluminum-silver alloy? The term "typewriting-machines" suggests that that text was written in the early 20th century. IP: Logged
