![]() ![]() Zinc Applicationsįrom outlets to radiators to nails, zinc casting is commonly used to make electrical, automotive, and hardware equipment. This layer acts as a protective coating from further reactions with air or water, which is why roughly one third of all metallic zinc produced today is used to galvanize other metals to prevent corrosion. When zinc is exposed to air it naturally reacts to the carbon dioxide in it and forms a layer of zinc carbonate. Brass is commonly used today for its corrosion resistance. Probably the best known alloy of zinc is brass, which is made by adding 55% or more copper to zinc. Popular zinc alloys are referred to by the acronym ZAMAK, for zinc, aluminum, magnesium and copper. Zinc is rarely used in its pure form but instead is used to form numerous metal casting alloys, including brass, bronze, nickel silver, soft solder, German silver, spring brass, and aluminum solder. This includes, boat fittings, jet engine parts, coastal architecture, or water filtration screens. Primary uses are for architectural paneling, kitchen equipment like pots, pans and cutlery, along railings, and also for the manufacture of springs, or marine equipment.Ĭomparatively, if your needs require exceptional toughness against corrosion with very excellent welding capabilities, then 316 stainless steel grade would be your prime choice. An austenitic stainless steel grade, it has a wide variety of industrial applications. The most familiar type of stainless steel is Type 304, or simply, 304. Modern stainless steel may contain such elements as nickel, niobium, molybdenum, and titanium to boost corrosion resistance, add strength and ductility to weather environmental factors that are found in climates ranging from tropical, dry, temperate, cold and polar found on land and sea, and even in the upper atmosphere and outer space. ![]() It comes in many different grades that are determined by the degree and combination of elements mixed with the iron, carbon, and chromium. ![]() Stainless steel is an alloy of iron, carbon, and a minimum of 10.5% chromium known for its strength and corrosion resistance. Stainless SteelĬhoosing stainless steel as an application over a zinc alloy will depend on a company’s needs. stainless steel will ultimately be determined by such factors as volume, costs, usage, and size, among other reasons determined by the marketplace. The process is ideal for manufacturing of high volume parts because of its dimensional accuracy, intricate detailing, and the ability to produce highly complex geometries. The casting process of any alloy involves injecting molten metal into a mold, or die, under high pressure to produce a particular shape. The finished product will have its own mechanical and physical properties that determine its longevity, durability, strength, and overall functionality. stainless steel as a material would depend on the specific applications each alloy is best suited for (this includes the casting of each alloy). Is this really doable on a small tap like this? Lastly, I think smacking the tap to try to break it up might be risky to the part, but I'm curious about how this might work on tiny taps, and whether it affects the thread in the part.Zinc alloys and stainless steel are common materials used for parts in many applications. I also read about milling them out at high spindle speed using carbide end mill. 015 dia to slip down into the flutes, waiting for some epoxy to set up right now.Will try that when ready. Ain't holiday weekends grand?Īnyway - can a HSS tap be burned out (EDM)in 304? I have made a tiny tap extractor (of course this is a 3-flute bottoming tap), using some music wire. next week, and the parts I'm working on are parts that need mods and fixes, so they belong to the customer. And the customer has a NASA project they are shipping Tues or Wed. To add to the fun, the 2-56 hole is centered down inside a cup about 9/16" ID x. Just looking for suggestions about best methods for tap removal per parameters in post title. ![]()
