Het valt weer niet mee om het in NL te bemachtigen.
Gelukkig is er internet.
Zamak 2 comes in an ingot that weighs approximately 4 pounds and measures 1" x 2" x 9" with tapered sides. This alloy has the same composition as Zamak 3 with the addition of 3% copper in order to increase strength by 20%, which also increases the price. Zamak 2 has the greatest strength out of all the Zamak alloys. Over time it retains its strength and hardness better than the other alloys; however, it becomes more brittle, shrinks, and less elastic. Zamak 2 is also known as Kirksite when gravity cast as for use a die.
Each ingot weighs approximately 4 pounds and measures 1" x 2" x 9" with tapered sides. Zamak 5 has the same composition as Zamak 3 with the addition of 1% copper in order to increase strength (by approximately 10%) hardness and corrosive resistance, but reduces ductility. It also has less dimensional accuracy. Zamak 5 is more commonly used in Europe.
