How big is a# 8 crucible?
Measurements: 7-1/2″ x 8-3/4″ (exterior dimensions); 6″ in diameter x 8″ deep (interior dimensions).
What type of crucible is used for aluminum?
Carbon-bonded and ceramic-bonded clay graphite and silicon carbide crucibles are widely use in melting and holding aluminum and aluminum alloys, aluminum-bronze, copper and copper-based alloys, cupro-nickel and nickel-bronze alloys, precious metals, zinc and zinc oxide. Crucibles also are used in melting cast iron.
How big is a #6 crucible?
Measurements: 6.75″ diameter x 8″ height (exterior dimensions); 5.5″ diameter x 7″ deep (interior dimensions). *The “#” in title represents the amount of aluminum that the crucible can accommodate (in pounds); the “Kg” is for the amount of kilograms of brass and copper capacities.
How big is a 5kg crucible?
Maximum crucible size is 11 lbs (5 Kg). Outside Dimensions: 8″ W x 12″ H (200 mm x 300 mm).
What size crucible do I need?
Use the size for which the furnace was designed. Crucible size refers to capacity of aluminum. For example, a #16 crucible holds 16 lbs of aluminum. Brass and bronze capacity is three times aluminum capacity ( therefore, a #16 crucible holds 48 lbs of brass or bronze).
Should I use borax when melting aluminum?
Pour a teaspoonful of borax into the molten aluminum. This will dissolve oxides and other dross remaining in the aluminum. Carry the crucible carefully over to the box filled with sand.
What is a foundry crucible made of?
Crucibles are traditionally made from ceramic materials, which can withstand very high temperatures. The material of your crucible should always have a much higher melting point than that of the materials you are heating.
Can you melt copper in a steel crucible?
Crucibles are made of steel, silicon carbide, and often clay graphite. They resist high temperatures and will hold and heat the copper you are melting. Keep in mind that you will also need proper tongs to grasp the crucible if you intend to pour your liquid copper solution into any molds.
