National Lead alloy?

[Slinger]

I've got a couple 1 lb. bars of National Lead 140. They registered 10 on my LBT. Any idea of what it is as far as tin/lead?

[sheepdog]

There was a "National Lead" out of Dallas. Their 1lb bars were 40/60, not sure on ingots. Use to say right on the bar "40/60".

Does any one know if this is 40/60 or 50/50 or ??/??

What is the alloy of most 22 rim fire target ammo ... see back ground.

With a hardness of 10, if just lead and tin it would be close to 20:1. But, it could also be WW alloy with that, or whatever else to get it to that hardness. Really no good way to tell except for finding out which alloy of theirs it is, and what that alloy contains.

As the the .22 boolits. They should be near pure, minus the copper plating.

Possibly a bar solder with high tin content?

What is the alloy of most 22 rim fire target ammo 3% Antimony 97% Lead.

http://dictionary.mechanicalengineering.tv/LEAD.htmlAntimonial lead is an alloy containing up to 25% antimony with the balance lead, used for storage-battery plates, type metal, bullets, tank linings, pipes, cable coverings, bearing metals, roofing, collapsible tubes, toys, and small cast articles. The alloy is produced directly in the refining of some lead ores, but much is also made by adding antimony to soft lead. The alloy is also known as hard lead, and in England it is called regulus metal. Much of the lead used in the United States is in the form of antimonial lead. The antimony hardens the lead and increases the tensile strength. The usual alloy contains 4 to 8% antimony and has about twice the tensile strength of pure lead. Up to about 0.10% arsenic stabilizes and hardens the alloy, and from 0.25 to 1% tin may be added to improve the casting properties. Antimonial lead, of NL Industries, Inc., for chemical linings, contains 6 to 8% antimony, has a density of 0.398 lb/in3 (11,016 kg/m3), and melts at 475 to 555°F (245 to 290°C). An antimonial lead with 6% antimony has a tensile strength of 4,100 lb/in2 (28 MPa) with elongation of 47%, as rolled. After heat treatment at 455°F (235°C) and aging one day, the tensile strength is 12,600 lb/in2 (87 MPa) with elongation of 3%.
A hard lead with 10% antimony and 90 lead has a tensile strength of 8,800 lb/in2 (61 MPa), elongation 17%, Brinell hardness 17, and melting point 486°F (252°C). Cable lead, or sheathing lead, used to cover telephone and power cables to protect against moisture and mechanical injury, contains about 1% antimony. The alloy for collapsible tubes usually contains 2% antimony. Antimonial lead may be used for machine bearings, but for this purpose it usually contains considerable tin and is classified with the babbitt metals. Hoyt metal, used for bearings, contains 6 to 10% antimony. Alloys containing from 70 to 90% lead, 5 to 20 antimony, and 2 to 20 tin have been used for railway
car bearings under the name of lining metal. Dandelion metal, used for locomotive crosshead linings, had 72% lead, 18 antimony, and 10 tin. Terne, a lead alloy containing 8 to 12% tin, is used to plate steel for corrosion resistance. Terneplate, as the coated steel is called, is widely used for automobile gasoline tanks and also has been used for roofing on buildings.

I have a partial bar of National Lead solder that has 111 instead of 888. Don't have a hardness tester but it must be high in tin since I had a hard time trying to bend it!

[Shiloh]

I have seen bar solder that looks almost identical to what you posted. I can't tel lyou the alloy composition though. Sorry.

I have 3 bars from National Lead marked 221 and have not been able to find any information on them.

[Paul]

Thanks you all, good info

& Thanks 243winxb for info on Railway Babbit, as I once melted some babbit off of the brass bearings of the old cars, just marked it so I would know someday.

I have a neighbor that has a 10 spot 22 range, they shoot once a month, he said come over and mine the lead out of the backstop.!! Great!! hope to get 1000# this summer by hand.

Yep, I have only casted off and on over the last 20 years, using borrow equipment, making say 300 to 400 bullets every 5 years...... But now, I have bought the Lee 20# Pot, have Three - 6-banger Lee molds, and 400+ lbs of WW, Lead, Babbit, some Pewer, etc and getting ready to cast. Plan on getting up to a ton of lead or more on hand soon.

Have been reloading since 1971, have over 10,000 primers on hand, and over 13,000 empty brass cases, my goal it to have on hand 10,000 + loaded rounds at one time. (never done that before)

about 5 years ago I loaded up about 5000 45ACP using Hornady 200 gr lead C/T and shot them one spring. Hey my scores inproved... I buy from MidwayUSA, and Graft & Sons.... I am less then 100 miles from both Columbia, & Mexico Missouri

If you ever get a chance Visit Sierra Bullet Factory in Sedalia, MO... Plus they sell bullets out the back door, scoop up just like a Candy Store in bulk. They will even take you on a tour of the place. & a 300 meter Underground Range.

I teach Firearms Safety & Shooting for Missouri's DOC part time.

Thanks again shooters, I'm new to this site, hope I didn't break any rules here. Hope I can add my .02 someday for you.

This site Shoots !! (rocks)

I used to work for NL some years ago.. We processed bauxite and shipped it to Cincinnati, IIRC


And Yes they had the "Dutch Boy" paints...
