Materials: Add Copper Alloys to Material-Metals (#25832)

Browse Source 
* Add Copper Alloys to Material-Metals

Added a set of Copper Alloys presented in Application Data Sheet
'cda144-8-mechanical-low-temperature.pdf, Nov1974'
Permission and Credit to the 'Copper Distributor's Association (CDA)'
These cards follow values for 295°K

Colours approximate values found by general search of images and
descriptions found on the internet and use FreeCAD's appearances.

* Add Copper Alloy general/generic information

This additional information appears as general info not affected by
anneal or cold drawn or aging factors.
Information found from pages C10200, C12200, C15000, C22000, C23000,
C44300, C46400, C51000, C61400, C64700, C65500, C70600, C71500, C95500

Also followed suggestions of adding tagging and description mentioned
in pull request.

* Add Copper Alloy source URL

Added the URL for the source Application Data Sheet
'cda144-8-mechanical-low-temperature.pdf, Nov1974'
This pdf is hosted by the 'Copper Distributor's Association (CDA)'

Here is the source URL for this pull request in case it's needed:

* Add Copper Alloy UltimateStrain for 102,122a,122b at 295°K

102=2.8%, 122a=39.7%, 122b=1.46%

* Add Copper Alloy UltimateStrain for remaining cards 150...955 at 295°K

105=4.13%, 220=41.5%, 230=40.4%, 443=82%, 464=31.8%, 510=3.6%, 614=27%
647=9.9%, 655=10.4%, 706=28.4%, 715=39.9%, 955=10.6%.

Removed spaces between IACS = nn%, so that it all stays on same line.

Added C95500 compressive MPa.
Added C64700 Si and IACS ranges.

Also looked at 'KindOfMaterial' for Steel and made similar edits based
on Table 2 info shown in brackets () to try keep a bit of consistency.

* Fix Ultimate Strain Description and Units

Ultimate Strain is the maximum stretch you can do to a material before it
gives up. This is associated with Ultimate Tensile Strength, which is the
maximum stress you can apply before the material starts to fail, elongate
and eventually fracture.

Units are of the type ΔL/L, such as, stretched 0.10in per 1.0in (10%), or
stretched 0.15mm per 1.0mm (15%). To avoid confusion, use 0.1 or 0.15 and
avoid using 10 as for 10% or 15 as with 15%, and just call it a fraction.

* Add Copper Alloy Elongation, Reduction of Area, Yield Strain, Toughness

Impact Charpy and Notch Tensile Strength are both considered as Toughness
There is currently no use for these in FreeCAD, but maybe a future use as
these are part of the Table 2 and better to add them now vs forget adding
them later. The Charpy test is a fast cost-effective standardized method,
and there are other more sophisticated impact tests that can be "better".
There are other tests than the notch tensile strength test, but it's also
a simple, fast, cost-effective method to create fracture toughness data.

While adding 'Elongation' and 'Reduction of Area' both these are referred
to as percentages (preferred over fraction), it seemed best to change the
'Ultimate Strain' to percentages too for consistency even though this has
was referred to as fraction or percentage when searching for definitions.

Added Yield Strain, probably not important now because the elastic region
is pretty small, but with smart metals that can do up to 5% bends then it
seems something worth adding it for that category of future metal alloys.

* Add Copper Alloy Isotropic, Linear, Toughness Temperature Arrays

* Add Copper Alloy Elastic & Toughness arrays and reduce model wordiness

Reduced wordiness of array models by cutting-out Metal and Temperature
as these are somewhat redundant words.

Added remaining ElasticProperties and PlasticTriaxialProperties.

* Add Copper Alloy Linear Elastic Temperature Arrays

Moved Elongation and ReductionOfArea after YieldStrain/Strength and added
FractureStrength so these are grouped together on the cards since they're
all related (Note: Material viewer resorts these alphabetically).

Linear Elastic arrays are set in the order of strain/strength for Tensile
then strain/strength for Yield, and then Elongation/FractureStrength, and
then ReductionOfArea.

Reviewed pdf again and corrected a few errors missed/made earlier.
