This alloy is the designers first choice for die casting applications and the most widely used in North America. Zamak 3 is a family of alloys with a base metal of zinc and alloying elements of aluminum, magnesium and copper. Zamak alloys are part of the zinc aluminium alloy family. It is the zinc-aluminum alloy one uses in die casting with the lowest possible aluminum content. Density is defined as the mass per unit volume. More than 70% of all North American zinc die castings are made from Zamak 3. Zamak 5 has the same composition as Zamak 3 with the additional of 1% copper in order to increase strength (by approximately 10%), hardness and corrosive resistance, but reduces ductility. 7075 is the preferred alloy. this is very evident in machining the material. Density of zinc alloy â Zamak 3 is 6.6 g/cm 3 (0.24 lb/in 3). Aluminum Composites Characteristics A-3-6-15 Guidelines 3-15 4 Copper Alloys 3-16 Selecting Copper Alloys 3-16 Copper Alloy Chemical Composition A-3-7-15 Standard 3-17 Copper Alloy Properties A-3-8-15 Standard 3-18 Copper Alloy Characteristics A-3-9-15 Guidelines 3-19 5 Magnesium Alloys 3-20 I prefer the aluminum frame 1911 mostly because of the weight loss in the material itself. Aluminum alloys contain almost no iron and without iron, the metal canât actually rust, but it does oxidize. Zamak 5 should be consider when moderately greater hardness strength and creep resistance is require over Zamak 3. Proudly Made in the USA. Interesting example, my Futur clone (Q-shave) has a Zamak head, but threaded parts appear to be made of aluminum or steel. The complexity of the part, the number of cores or pulls, the engineering and Zamak 2 Ingot (Aluminum 4%, Copper 3%, Zinc 93%) - Kirksite. Zamak 3 is the de facto standard for the zamak series of zinc alloys; all other zinc alloys are compared to this alloy. Zamak is a high grade form of Zinc. In mild acidic solutions (pH range of 4.0 to 7.0), the ZA alloys are more corrosion resistant than SHG zinc or the Zamak alloys, with the ZA-27 alloy performing better that ZA-8 and ZA-12 due to its higher aluminum ⦠We're one of leading Zinc Die Casting Parts manufacturers and suppliers in China, also supporting customized service. It has excellent castability and long term dimensional stability. the alloy is important. ... the housings you see may be diecast in a zinc-alluminum alloy sometimes refered to as Zamak. These include ZA-8, ⦠Aside from typically being labeled junk and SNS, what's everyone's impression on zamak framed autos in terms longevity? There are to many variables to give a simple answer. Zamak is a family of alloys with a base metal of zinc and alloying elements of aluminium, magnesium, and copper. Zamak die-casting: let's explain it . its tensile strength is much higher than the more common 6061 alloy. It features an aluminum content of 8.4 percent with one percent copper. $17.99. The name âZamakâ is an acronym of the names of the metals of which the alloys are composed: Zinc, Aluminium, Magnesium and Copper (or Kupfer, in German.) Joined Apr 22, 2011 Messages 4,063 Reaction score 1,922. It is the most commonly used in Zinc die casting, providing an excellent combination of strenght, ductility. Only 14 left in stock - order soon. IE, you won't see steel and aluminum together. It's made of milled aluminum, but aside from the oversized threads for barrel and buffer tube, it ⦠When the alloy is exposed to water, a film of aluminum oxide forms quickly on the surface. Figure 2 shows the effect of pH on the corrosion rates of ZA-27 in relation to zinc and aluminum. Find quality and precise zamak 3 VS zamak 5 material properties made in China with our factory. The string spread is a bit wider from E to E on the tone pros. It is still Pot Metal, but is 5% Aluminum. Great tone improvement. Get Quote. JWH replied to SocProf's topic in Gibson USA. ZA-8 is the only hot chamber alloy of the three. Just not enough "oomf" to blow the thing apart. A salt spray test was used to simulate the relative corrosion behavior of ZA-8, ZA-12, ZA-27 and No.3 alloy as compared to that of pure zinc and aluminum or aluminum-rich alloys. zamak 15 is a zinc alloy of high quality with many advantages: it is comparable to the zamak 12 as regards the tensile strength and the zamak 13 with respect to the corrosion resistanc and impact strangth. Tone pros rocks because of the the little set screw that locks it to the bridge post. F) 718 - 728 707 - 759 708 - 903 1035 - 1100 1000 - 1100 1630-1650 Coef. Zamak 3 has the base composition for the Zamak alloys (96% zinc, 4% aluminum). Density of typical aluminium alloy is 2.7 g/cm 3 (6061 alloy). Contributor. Gibson specs are a 2 inch spread. Eastern Alloys is North America's largest manufacturer of zinc alloys for the die casting industry, manufacturing a complete range of high quality zinc die casting alloys including Zamak 3, Zamak 2, Zamak 5, Zamak 7, ZA-8, ZA-12, ZA-27, EZAC and ACuZinc. Aluminum and Zamak can be short lived or last for generations. The other ZAMAK alloys: ZAMAK 2, ZAMAK 5, and ZAMAK 7; have a similar range of Aluminum but differ with their Magnesium and Copper ranges thus resulting in different mechanical and physical properties. Zamak 3 die casting is the standard for the Zamak series of zinc alloys; all other zinc alloys are compared to this. Zamak â Zamak 3. Please be free to place orders. It has excellent castability and long term dimensional stability. Jan 19, 2014 #5 I just swap saddles on the Nash for TUSQ ones and voilà! Most "pot metal" is aluminum based though. The hard oxide layer is quite resistant to further corrosion and protects the underlying metal. Production of Aluminum Castings The following charts are intended to provide a relative guide to compare various aluminum casting methods. Zamak 3 has the base composition for the zamak alloys (96% zinc, 4% aluminium). Give it the magnet test, it's either going to be steel based or aluminum based, and I highly doubt it's stainless. When it comes to miniature die castings , zinc is definitely the route to take. For low pressure rounds like the .22 short & .25acp I don't' worry too much about it exploding in my hand. I assume that your idea was to stick zamak lugs onto the receiver cover that you can pound on them. The most recent addition to the ZAMAK family is the new high-fluidity or âHFâ alloy. icantbuyafender Senior Member. Don't know which one lasts longer, but they didn't decide to build airplanes out of Zamak, so that at least gives us something to think about. The most common zinc alloy, ZAMAK 3, satisfies most die casting needs with it's high strength, hardness and low melting point. Jun 12, 2017 #3 HDSledge. Zamak zinc-aluminum alloy sucks compared to aluminum, steel or brass. More than 70% of all North American zinc die castings are made from Zamak 3. Zamak â Zamak 3. Because of the minimal aluminum content, ZA-8 has a lower melting point and higher density than other zinc-aluminum alloys. Location 4200 N. Nordica Norridge, IL 60706. 10-14-2006, 05:39 AM #4.
