can you melt brass in a cast iron skillet?

admin — Wed, 11 Jan 2012 00:18:26 +0000

Technically, yes you could because brass melts at about 950 while cast iron melts around 1,300 F.

You would do better to buy some ceramic crucibles. You can find them on the internet and sometimes used ones on Ebay. They’re cheap. You must be very careful handling molten metal. A crucible makes it easy, certainly easier than a cast iron skillet. I learned my lesson the hard way when some molten lead accidently dripped into my shoe.

By using a skillet are you intending to use a kitchen range? If so, you won’t get the temperatures necessary to melt brass. I use two propane torches in a home-made refractory smelter.

Is it possible to cast bullets out of brass?

admin — Fri, 30 Dec 2011 00:43:19 +0000

Would brass be too hard for the barrel? I mean, people use lead with copper, brass jackets, but why don’t people cast bullets from solid brass? I actually was wondering this, because there are some people who shoot a lot of .22 and a lot of centerfire could theoretically use .22 brass to cast bullets for their centerfires. Anyone know if that’s possible?

Brass would be a poor choice to cast bullets. Lead is far heavier and softer and allows for expansion. Jacketed bullets always have a lead core. To make a bullet out of solid brass you would have to reconfigure your powder load. Lead core bullets, being heavier than pure brass, require a load that will provide the velocity and the impact required for that caliber.

what is cast brass and what is it’s composition?

admin — Sun, 31 Jul 2011 06:44:52 +0000

Cast brass is just molten brass that has been poured into a shape and allowed to set. The process is called casting.

There are many different compositions of brass. You can see a whole list of them at http://en.wikipedia.org/wiki/Brass but generally brass is about 60-65%Copper and 35-40% zinc.

Red Brass is probably the most widely cast brass composition. It is popular for ornamental fixtures because of its deep reddish color. The material is composed of approx. 85% Copper, 5% Lead, 5% Tin, and 5% Zinc.

Gilding metal is made up of 95% copper and 5% zinc, it’s a type of brass. Does this mean it has lead?

admin — Sat, 23 Jul 2011 15:59:56 +0000

If so, is it dangerous? Is it safe to work with? I’m going to be casting this metal. If it’s made up of 95% pure copper and 5% pure zinc, that totals 100%. There can’t be more than 100%, and … Continue reading →

What is the current resale value (scrap) for copper, stainless steel, aluminium, iron, brass, cast iron, steel?

admin — Tue, 12 Jul 2011 12:25:13 +0000

Hi all, I’m looking into starting my own scrap collection company and I’m wondering what the resale is of the above metals and anymore common ones that you can think of. It’s seems to be quite difficult to source this information in sterling. Also in the quantities to what I am familiar with i.e. kilos and tonnes. All answers would be greatly appreciated and any references would be taken kindly as well.

Thanks all

Click on the link on the left hand side in blue that says UK scrap metal prices. You may find the weights in imperial this is because the USA still uses imperial, so most scrap is priced this way.

What year did men start wearing their belts really tight?

admin — Mon, 30 May 2011 14:56:17 +0000

Nowadays I hear women and the media making noise about "real men". When did being a man become more than being a homosapien with a penis?

Worse Still hypocrits (even the men) call you a sexist bigot when you say real women are in the kitchen

IF being a man means being whipped by females and the gays I dont want any part of that. We live in a society where having brass balls and a cast iron rod is looked down on society.

I remember in the 70′s, all the women had cameltoe, i miss those days.

Rockwell and Vickers hardness of 1018 steel and other metals?

admin — Thu, 14 Apr 2011 23:16:07 +0000

I cannot find a legitamate site that gives me the Rockwell or Vickers for 1018 steel, gray cast iron, or brass.

I have experimental values and need to compare them to hardness numbers used in industry. If anyone could give me the hardness numbers or a website that would have some sort of chart for them that would be great

Matweb is an online material database. It has data sheets on just about any material you could want.

doesn’t rust

Trying to connect PVC p-trap to brass/iron drain, with a bit of a problem…?

admin — Fri, 08 Apr 2011 12:00:56 +0000

I am trying to change drain pipes in my bathroom.

The old drain pipes were Brass, but right now I am putting PVC.

The problem is that at the end of P-Trap, the original Brass Nut that connected Brass P-trap to drain (which is cast iron) is still attached and would not get loose because of the rust.

How can I connect PVC p-trap to it?

First, try heating the brass gland nut with a propane torch. Brass expands faster than iron, and this might break it loose for you. If this doesn’t do it, get out the Dremel and a few heavy cutting wheels, and slice it up the side till it’s almost to the threads, then separate it with a chisel or big (cheap) flat blade screwdriver.
