When it comes to zinc die casting, there are two basic families. Zamak is most often than not the "mysterious metal" from zippers, buttons, cases, that loses its luster in air rapidly and is brittle. If you're just looking for the color, try eastwood. Zamak 5 (ASTM AC41A) or Zinc Alloy 5, is the most widely used zinc alloy in Europe. They have a yellow cad finish that imitates the original. There are four alloys in the conventional zinc group, which are often referred to commercially as the “Zamak” alloys (an acronym for zinc, aluminum, magnesium and copper). That's what becomes of using Zamak for gun manufacture. Zamak (formerly trademarked as ZAMAK), also known as Zamac is a family of zinc alloys widely used in common everyday items. The most common zamak alloy is zamak 3. The real problem is not guns like the Davis, which everyone knows is cheap, it's all the fine old firearms names that used to mean quality materials and workmanship, but now often also means zinc based white metal. It is used in die-casting manufacturing and it has higher aluminum levels than any other alloy. Zamak alloys (particularly #3 and #5) are frequently used in the spin casting industry. HisSoldier, Jan 1, 2013 #15. The term "pot metal" came about due to the practice at automobile factories in the early 20th century of gathering up non-ferrous metal scraps from the manufacturing processes and melting them in one pot to form into cast products. Excellent physical and mechanical properties High-pressure zinc alloy die casting is one of the most efficient and versatile high-production methods used for manufacturing strong, accurate, and complex metal components. This is why Zamak jewelleries are firm and solid. The hardness gives a bold look and it … It has a higher copper content than Zamak 3, which results in higher strength It has less ductility (decreased elongation) than Zamak 3 The hardness gives a bold look and it has a long lifespan. It is part of die-casting manufacturing and it has higher aluminium levels than any other alloy. Zinc is also known as Zamak alloy: Zamak 2, Zamak 3, Zamak 5 and Zamak 7. This is why Zamak pieces of jewelry are firm and solid. Zinc (zamak) is known for its high strength, accuracy, ductility, ease of casting, high thermal and electrical conductivity, and long life. Joined: Pot metal (or monkey metal) is an alloy of low-melting point metals that manufacturers use to make fast, inexpensive castings. While zamak is held to higher industrial standards, it is still considered a pot metal. These alloys are most commonly die cast. MedWheeler Member. Die casting started in the automotive industry and it is still widely used in the manufacture of automotive components. The conventional, or ZAMAK alloys, are commonly named based on their sequential development. Zamak is a mix alloy of zinc aluminium magnesium and copper that is dipped in silver. These alloys, with their ASTM designations, are: As such, the zinc die casting is applied in the manufacture of high quality industrial and building materials. Its popularity is due to an excellent balance of desirable physical and mechanical properties, superb castability and long-term dimensional stability. For example, Zamak 3 (ASTM AG40A), or Zinc Alloy 3, is the most widely used zinc alloy in the zinc die casting industry and is usually the first choice when considering zinc for die casting for a number of reasons.It provides the best overall combination of strength, castability, dimensional stability, ease of finishing, and cost. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used. Alloy 3: (ZAMAK 3, ZP3, ZL3, ZP0400, ZnAl4, ZDC2) Alloy 3 is the most widely used zinc alloy in North America. I used HCl to test the zinc coating thickness on galvanized steel. It would take about 30 seconds to completely remove the zinc from a piece galvanized sheet metal. Most cast zinc parts are some grade of zamak, 3, 5 or 7. Zamak is a mixed alloy of zinc, aluminum, magnesium, and traces of copper that is dipped in silver.
