properties of CuAg1

(OP)
Hi there,

for a calculation, I need the mechanical properties of CuAg (used in rotors of E-motors). Can anyone help me on this?

tnx
rob

RE: properties of CuAg1

Maybe not exactly Cu-1%Ag alloy, but several alloys designated CuAg or similar.

Several wrought alloys from Europe designated 'CuAg' but << 1% Ag:
Cu-Ag [Netherlands] Symbol: Cu-Ag Standard NEN-ISO 431 Cu+Ag: 99.9
Cu-Ag [International] Symbol: Cu-Ag Standard ISO 431 : 1981 Cu+Ag: 99.9
 CuAg [Germany] Number 2.1202 Standard [[DIN 17666 : 1964 bis 1970]] Ag  0.025-0.25  (others, 0.1).
CuAg [Poland] Number MS Standard PN / H-87053 : 1979 contains 0.045-0.25% Ag, (others, 0.1).

Also, 'Cu-Ag-1 [Great Britain]' Number C101 Standard BS 6017 : 1981 contains 0.01-0.027% Ag.
Crosslisted to UNS C11300 which has properties available for many different tempers; e.g., see
http://www.matweb.com/search/SpecificMaterial.asp?bassnum=MCUAAH02aa

Several American Cu casting alloys have 1 wt% Ag (actual range 0.75-1.25%) but also other strengthening elements which reduce conductivity.  Used in the heat-treated (precipitation hardened) condition. Normally used for resistance welding electrode tips & electrical switches.
UNS C81700: Ag 1, Be 0.4, Co 0.9,Cu 94.25 (min), Ni 0.9.
http://www.matweb.com/search/SpecificMaterial.asp?bassnum=MCUDAJ

Similar is UNS C81800: Ag 1, Be 0.4, Co 1.5, Cu 95.6 (min). Mechanical properties about 10% stronger than for C81700, but elongation is less: 3% (min). vs. 5% (min).
%IACS = 48%.

Some high-conductivity (100%IACS) American copper alloys (C10700, C10940, C11600) given in ASTM B152 & B187 contain 0.085% Ag (min). These are available in a wide range of tempers, with YS from 69 to 310 MPa in 6 mm thickness. E.g.,

If you can determine the applicable standard and whether 1%Ag, maybe more info.

RE: properties of CuAg1

Rob,
Ken covered most of the bases, but the question to start with is what alloy are you dealing with?  You need a USN number or a EN number to specify the alloy.
Generic names don't count unless you only want generic answers.

(OP)
Don't really know the exact type Ed, but I think I have enough by using the data Kenvlach gave me. I need basically E-modulus and an indication of yield stress (and density), in order to make a FEM calculation of the rotor of an E-motor.

RE: properties of CuAg1

The modulus of all of these alloys is very similar.
The strength, creep resistance, conductivity (and hence temperature) can be very different.
You may need to do this with a couple of different alloys to see how sensitive you are to the exact properties.
