Composition of Metals

Post by Jammer »

This is a list of alloys from the other site. It hadn't tranferred and I'm afraid it will be lost. I don't have most of the list myself. Until now.

This is a post where I will try to put all the alloys, so we won't have to hunt through the whole thread for something.

Non-Ferrous Alloys
Ampco A18 Aluminum Bronze
Al - 8.4%
Fe - 3.75%
Mg - 0.7%
Mn - 0.1%
Cu - 86.4%

Brass Round Stock
Cu - 54.5%
Zn - 41.7%
Sn - .22%
Pb - 2.9%

Brass Round stock #2
Cu - 76.4%
Zn - 4.6%
Sn - 9.9%
Pb - 6.4%
P - 1.2%

Brass Propand tank valve, Sherwood
Cu - 54.6%
Zn - 42%
Pb - 2.1%

Brass Ball Valve, Apollo USA
Cu - 75.6%
Zn - 11.6%
Sn - 5.1%
Pb - 5.3%
P -0.7 %

95/5 Solder, Lead Free
Sn : 97%
Sb : 2.6%
a few trace elements.

--------------------------------------------------------------------------------

#1 Aluminum Wheel Alloy
Al - 91%
Si - 8.5%
Fe - .42% (questionable)

#2 Aluminum gas Grill Alloy
Al - 80.5%
Si - 15.6%
Cu - 2.4%
Zn - .80%
Fe - .88% ??

Aluminum Pop Can
96% Aluminum

Piston alloys:
2618:
from matweb:
http://www.matweb.com/search/DataSheet. ... T61&ckck=1

Aluminum, Al 92.4 - 94.9 % As remainder
Copper, Cu 1.90 - 2.70 %
Iron, Fe 0.90 - 1.30 %
Magnesium, Mg 1.30 - 1.80 %
Nickel, Ni 0.90 - 1.20 %
Other, each <= 0.050 %
Other, total <= 0.15 %
Silicon, Si 0.10 - 0.25 %
Titanium, Ti 0.040 - 0.10 %
Zinc, Zn <= 0.10 %

4032:
http://www.matweb.com/search/DataSheet. ... 324e592396

Aluminum, Al 81.1 - 87.2 % As remainder
Chromium, Cr <= 0.10 %
Copper, Cu 0.50 - 1.30 %
Iron, Fe <= 1.0 %
Magnesium, Mg 0.80 - 1.30 %
Nickel, Ni 0.50 - 1.30 %
Other, each <= 0.050 %
Other, total <= 0.15 %
Silicon, Si 11.0 - 13.5 %
Zinc, Zn <= 0.25 %


from nasioc:

-- 2618 conducts 6% more heat, which is good for keeping the piston cool under high-load, but bad for keeping combustion warm under low-load. Because a 2618 piston will be a little cooler, it may not need the full 15% greater clearance compared to an otherwise identical 4032 piston, which would be hotter under the same load.
-- 4032 is 4% harder and has a 6% higher modulus of elasticity, which is probably at least partly responsible for its superior wear characteristics.
-- 4032 is 3% lighter, which somewhat offsets its reduced strength.
-- Per square inch, 2618 has only 13% greater fatigue strength, even though the ultimate strength is 16% higher and the 0.02% yeild strength is 17% higher. (The fatigue strength is the most important one for a daily driver.)
-- Per pound, 2618 has only a 9.5% greater fatigue strength instead of 13%, and only a 13%, instead of 16%, higher ultimate strength.

These spikes were left along the tracks near my house. I noticed the new spike had markings on top MC, a number 6, and a monogram CO, I think.

Old Railroad Spike, no markings
C - 0.30
Mn - 0.80
Si - 0.25
Cu - 0.025
Cr - 0.10
Ni - 0.12
Sn - 0.02
V - 0.002

New Spike, Marked MC
C - 0.25
Mn - 1.00
Si - 0.23
Cu - 0.32
Cr - 0.10
Ni - 0.11
Sn - 0.02
V - 0.026 The major difference in the two, Vanadium makes it stronger without effecting the ductility of the metal much.
