What temp should lead be for casting bullets?
Re: Bullet casting temperature. I cast 16+1 lead/tin at about 720-730 F Works for me, also dipping in Lyman Magdipper pot.
How hot does Lee lead pot get?
900 degrees Fahrenheit
Large, stable base for safety. 4″ of clearance under the spout is high enough to accept all brands of bullet molds and most sinker molds. Melter is capable of reaching 900 degrees Fahrenheit.
What is flux used for in bullet casting?
Fluxing keeps the physical characteristics of the bullets being produced uniform, and uniformity is one of several important criteria necessary for making bullets that will shoot accurately.
What temp does pure lead melt?
621.5°F (327.5°C)Lead / Melting point
Can you flux lead with borax?
The borax doesn’t seem to do much of a job on lead. Instead buy a wax toilet ring (gasket) and use about 1/4 teaspoon per 10 lbs., yes, it will burn quickly, so as soon as it hits the melted lead, start stirring and ignore the flames. The dross will float to the top and you can skim it off.
How do you remove impurities from lead?
The Harris process of softening and dezincing is designed to remove impurities from desilvered lead by stirring a mixture of molten caustic salts at a temperature of 450–500 °C (840–930 °F) into the molten lead. Metallic impurities react with the chemicals and are collected in the form of their oxides or oxysalts.
Can Borax be used to flux lead?
What is Marvelux?
MARVELUX. Marvelux Casting Flux is a very low fuming, minimal odor, nontoxic flux. I have used this flux for many years. Designed for casting the finest cast bullets possible. Helps keep your pot free from rust, reduces dross and increases alloy fluidity.
Can you melt lead with a propane torch?
Apply direct heat to the pan until the lead melts completely. If you’re using a handheld torch, light it up according to the product instructions and wave the flame back and forth right over the lead in the pan. For a propane burner, light it according to its instructions and set it to high heat under the pan.
Does melting lead give off fumes?
The cutting, grinding, or melting of lead at home is an unsafe practice. When you melt lead it creates airborne particles (fumes), or when you cut or grind lead, it can generate dust that can easily spread throughout an area.
Why do you put borax in molten metal?
Cover flux to prevent air oxidation: During melting, borates will protect metal from the oxidizing atmosphere of the furnace. Borates near the bottom of the furnace will melt last and float up to the surface of the molten metal dissolving oxides, silica (sand) and other non-metallic impurities.
At what temperature does lead melt?
Can lead be purified by electrolysis?
Lead metal is purified by electrolysis in a similar manner to copper; the electrolyte is lead (II) hexafluorosilicate PbSiF6 .
Why is borax a good flux?
Borax is used as a flux when forge welding to prevent oxidation of your surface and weld. The best type of borax to use is generally anhydrous borax (Amazon affiliate link), as it speeds up the process due to its early liquefaction, and leaves little room for impurities to get inside the joints in your weld.
What is the best thing to melt lead in?
A cast-iron skillet, aluminum slotted spoon, and aluminum ladle make a good starter set for DIY lead melting, but make sure you use them only for this task—never for cooking food! Since lead melts at 621 °F (327 °C), you also need a powerful yet reasonably safe heat source.
At what temp does lead melt?
Do you have to wear a mask when melting lead?
When melting Lead or cleaning up any Lead spillage protective clothing must be worn, this would include eye protection, gloves and an approved face mask. This precaution also applies if Lead dust is present.
Does melting lead give off toxic fumes?
How do fluxes work?
These formulations are commonly based on borax, or other boric acid derivatives. The way these commercial fluxes work is to combine with the oxidized components of the alloy (including any oxidized tin) and form an insoluble molten borate glass, which collects on top of the melt as a dark molten crust.
Why do we use flux in casting bullets?
What we want a flux to do is to remove those impurities that affect the surface tension of the alloy and cause problems during casting (most notable here are things like calcium, aluminum, zinc and copper). In addition, we want to remove any wettable particulate matter that might go on to form inclusions in our bullets.
How do I remove the activated carbon from the lead-pot?
Halfway through the pot, the lead-pot is stirred again, this time the activated carbon (dross) is removed.
