Due to the temperature during transportation, the gallium in the bottle may be in solid or liquid form when the package arrives, which is a normal phenomenon. Put the bottle into hot water, and the gallium inside will melt into a liquid state. Pour the melted gallium into the mold and freeze it in the refrigerator, it will solidify into a solid. BulletPoint5 : Wide Application: these zinc metal rods are versatile and can be applied in many applications, making them a reliable choice for different environments; For example, in ship construction, zinc anodes are often installed on ship hulls, water tanks inside ships, etc., to protect the ship hull from seawater corrosion by sacrificing themselves; You can trust them to extend the usage time of your equipment, also suitable for laboratory science and electroplating experiments Color : Silver GradeRating : 99.999% ItemForm : Sheet ItemName : RotoMetals Zamak 2 Ingot Whole (4% Aluminum, 3% Copper, 93% Zinc) ItemPackageDimensions_Height : 13.7922 centimeters ItemPackageDimensions_Length : 0.7112 centimeters ItemPackageDimensions_Width : 12.0904 centimeters ItemPackageQuantity : 1 ItemShape : Irregular ItemTypeKeyword : specialty-non-ferrous-metals-raw-materials Manufacturer : RotoMetals Material : Germanium ModelNumber : Germanium_5g NumberOfItems : 1 PartNumber : AM0132 ProductDescription : Zamak 2 comes in an ingot that weighs approximately ~ 4lbs (3.8lbs - 4.2lbs) and measures 1" x 2" x 8.5" 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.
