Electrum is silver + gold[edit]

I realize that a reference is given here, calling nickel-silver "electrum", but my opinion is that this is a misuse of the word. — Preceding unsigned comment added by 12.197.80.66 (talk) 19:23, 23 October 2013 (UTC)[reply]

Musical instruments (esp. saxes)[edit]

Could someone please provide sources for the musical instrument production? I was particularly surprised by the long list of saxophone brands supposedly offering nickel silver saxophones - I'm only aware of Keilwerth's "Shadow" range^[1]^[2]. Are we sure all those other brands make saxes of solid nickel silver (meaning the sax body and bell are made of it), or should I understand that NS is used in their production, e.g. for the keywork only? --HAdG (talk) 10:05, 29 March 2009 (UTC)[reply]

I can't say about the saxes, which seemingly are usually made of brass, but I can point out that the banjo rim hardware as shown in the photo is almost certainly nickel-plated brass, not nickel silver. Nickel silver doesn't take that high a polish where pure nickel does, so the difference is not difficult to spot. Also, nearly all high quality banjos beginning with those made in 1875 and going forward to today do indeed include brass or pot metal metal parts, plated either with nickel or gold.

toxicity questions[edit]

I have a fork that set in chinese food over night, the next day a blueish green deposit was found on the fork. I put the fork under magnification and the words, "Federal Solid Nickel Silver" were imprinted. Given that Copper promotes cirrhosis (see Merck Manual,17th edition, page 56 under Copper toxicosis), and the ease that these materials seem to leach out their metallic ions, such utensils should not be used except as ornaments.

See: Indian childhood cirrhosis, non-Indian childhood cirrhosis and idiopathic copper toxicosis in the Merck Manual.

Note: removed reference to cadmium, it a long time ago that I made this comment with toxicity questions, so if I had a reason I don't remember it.

^^^Speaking of which, can someone who knows please clarify why an article about nickel+copper+zinc is referencing the health effects of cadmium? This is the only place in the whole article where cadmium is mentioned, and there is no apparent reason for it. deusexaethera

I've changed the description of EPNS. See [1] or [2] for some justification.

I don't think the process described in the removed text is physically possible, let alone common! Removed text:

Because it has a finish which emulates silver it is often deposited onto a base metal to give a 'silver' finish. This depositation is usually done by electroplating and items are often marked as EPNS

'A typical industrial alloy is 45% copper, 5% nickel, and 8% zinc' 45 + 5 + 8 = 58% - so what constitues the other 42% of the mixture?

Yes what a mess! - I have replaced this with -- A representative industrial formulation (Alloy No.752) is 65% copper, 18% nickel, 17% zinc. --mervyn 15:23, 13 August 2005 (UTC)[reply]

Make up your mind, is zinc necessary or not?[edit]

"Nickel silver is a metal alloy of copper with nickel and often but not always zinc."

"There are many different formulations of alloys which fall within the general term of "Nickel Silver". All contain copper, nickel and zinc"

Does this mean that it may be called "Nickel Silver" with a capital "N" and "S" only if it contains zinc? Or what? -- Smjg 15:45, 8 June 2006 (UTC)[reply]

material properties[edit]

What is the melting point of a given composition? 121.45.242.151 21:02, 30 May 2007 (UTC)[reply]

Looking around, seems to be shy of 1000 °C. Varying compositions probably make it impossible to give a solid number or even a good range. But a good source of some rough estimates would be nice. 85.23.51.77 (talk) 11:57, 27 May 2009 (UTC)[reply]

Can someone add density and hardness (or Young's modulus) data for common compositions (eg so we can compare to silver) ? Found Nickel_silver mechanical properties with data for annealed UNS C76200 (~59% Cu, ~12% Ni, ~8% Zn, ~1% other) : Hardness = 75 Rockwell F. Rod57 (talk) 23:36, 11 February 2011 (UTC)[reply]

Please would someone skilful and knowledgeable add to the article's text a clearer link using that same link (Reference 5)(http://www.makeitfrom.com/data/?material=Nickel_Silver) which goes to a site that has pages for nickel-silver's physical and electrical properties etc ? And/Or (with permission if required) copy the data on nickel-silver from that site to add to the article ? Darkman101 (talk) 20:41, 5 October 2011 (UTC)[reply]

Is this the same as "cupronickel?"[edit]

Is this alloy the same as "cupronickel?" If so, shouldn't the articles be merged? —Preceding unsigned comment added by 69.41.40.21 (talk) 14:46, 29 March 2011 (UTC)[reply]

Setting up WikiProject Silverware?[edit]

Would anyone be interested in helping to set up a WikiProject Silverware? I'm interested in salvers, coffee pots, jugs, candlesticks, famous silversmiths, different styles, etc. Thanks. Girlwithgreeneyes (talk) 11:35, 3 April 2012 (UTC)[reply]

Terminology.[edit]

Alpacca is copper with 15-25% Ni and 20-35% Zn. In case of lower nickel content, its silverly colour becomes yellowish, which is called pakfong. When alpacca is plated with silver, it is called china silver. 87.97.105.148 (talk) 13:27, 8 August 2015 (UTC)[reply]
