Group: Renaissance Man Hero Member Posts: 2765	Hi Chet. The " purer " the Iron, the better, those specifications look quite good. It's just dawned on me that NMR might play a part in the process like the Meyer Mace device ?? Cheers Graham. --------------------------- Nanny state ? Left at the gate !!

Group: Ambassador Hero Member Posts: 4045	AISI 1008 and 1026 carbon steel seem most likely available Steels containing mostly carbon as the alloying element are called carbon steels. They contain about 1.2% manganese and 0.4% silicon. Nickel, aluminium, chromium, copper and molybdenum are also present in small quantities in the carbon steels. AISI 1008 carbon steel has excellent weldability, which includes projection, butt, spot and fusion, and brazeability. The following datasheet will provide more details about AISI 1008 carbon steel. Chemical Composition The following table shows the chemical composition of AISI 1008 carbon steel. Element Content (%) Iron, Fe 99.31-99.7 % Manganese, Mn 0.30-0.50 % Carbon, C 0.10 % Sulfur, S 0.050 % Phosphorous, P 0.040 % Physical Properties The physical properties of AISI 1008 carbon steel are outlined in the following table. Properties Metric Imperial Density (composition 0.06% C, 0.38% Mn, 0.01% Si, annealed at 925°C) 7.872 g/cm3 0.2844 lb/in³ Mechanical Properties The mechanical properties of cold drawn AISI 1008 carbon steel are tabulated below.

Group: Ambassador Hero Member Posts: 4045	Jim Thanks ,seems you landed the holy Grail......and I learned something new ?? [almost.... hopefully more after I speak with them on Monday] if iron holds some secrets towards excess energy harvesting , this info seems crucial towards understanding micro environments which can happen in these experiments . your link again http://www.goodfellow.com/E/Iron-Rod.html snip Depending upon the temperature, pure iron can exist in three forms, namely alpha-, gamma- and delta-iron; alpha iron is a polymorphic form of iron which is stable below 906C; it has a body centred cubic lattice (bcc) and is magnetic up to 768C. Gamma iron is a polymorphic form of iron which is stable between 906C and 1403C; it has a face centred cubic lattice (fcc) and is nonmagnetic (n.b. its range of stability is reduced by the presence of carbon, manganese and nickel and it is the basis of the austenite solid solutions). Delta iron is the polymorphic form of iron which is stable between 1403C and the melting point; it has the same lattice structure as alpha iron. end snip ============================================================== here is ions historical link for a reference to the time frame of the patent and where wire technology was in Cook's time [patent date 1871 as ion said " a good read" [fascinating techniques ,time period information and evolution , http://fortepianos.com/iron%20wire.pdf ----------------------------------------------- on a side note makes me wonder about a whole new group of experiments under heated conditions ,and whether the anomalies seen in micro environments [Like Mikes damaged stainless,or Celani and other ] can be better understood and utilized for true excess energy harvesting . « Last Edit: 2018-12-09, 14:16:30 by Chet K »

There's a firm in the UK that sells pure Iron to the Blacksmith trade. Max diameter of 30 mm. Dear Grum Cook points out that the finer the wire for the core, the better, probably to reduce eddy currents which were also probably not well understood at that time. Discovered probably by empirical observation (Eureka! the unit made from fine iron wire does not get as hot in operation as the one made with a iron bar and also puts out more useful energy!) I'm betting cook used ordinary iron annealed baling wire or soft iron music wire commonly available at that time so no high purity required, but would be an upgrade. I'm guessing around 0.062 dia for the rods would suffice, 2 to 3" packed dia. by 3 to 4 ' lengths. Also note that thermocouple grade iron wire type "JP" is 99.9+ purity, (see attached chart) and is also quite inexpensive @ $26 per kilo or less. https://ualloy.en.made-in-china.com/product/oBlxrDRjnCWi/China-Pure-Iron-Thermocouple-Bare-Wire.html Even from China this wire must meet all certs or temperature measurement using it would be in large error. I'm sure it can also be had from US suppliers at low cost, as it is not considered valuable and rarely worth salvaging for scrap. If you buy the thermocouple pair "J" wire, you get one Iron "JP" and one Constantan "JN", the Constantan being useful for Celani experiments.....serendipity! We need not look to anything exotic here considering the period of it's availability. "JP" Iron is "positive" thermoelement "JP" Constantan is "negative" thermoelement Together they form a type "J" thermocouple for temperature measurement.

Hero Member Posts: 1579	If the pig iron is quoted with 3% carbon and steel is quoted (elsewhere) with around the same, then this pig iron is probably not iron at all. If the SG specifies R45 or R60 gas welding rods, these might be worth trying.

Group: Renaissance Man Hero Member Posts: 2765	Hi Paul. The term " pig Iron " goes way back to the fist " Iron masters " the Darby's John Wilkinson etc. So named because the " floor " resembled piglets suckling from mother Pig. This was the first " Iron " from the smelting of ore and charcoal and later coal as the process cleared the entire area of trees! This Iron was then re melted to further alter its composition using the " art " of the time. If you're living in the UK I would greatly urge a visit to Coalbrookdale in the Midlands, a working " industrial heritage " museum and close to the worlds first true " Iron bridge " Cheers Graham. ------------------------ Daniel McFarland Cook discussion board // related to replication 1009110_b4012cf7.jpg (141.14 kB, 640x479 - viewed 711 times.) --------------------------- Nanny state ?

Hero Member Posts: 1579	Yes, I'm in Britain. The attached building belongs to that era. It is remarkable. Presumably, you need iron and not steel because iron takes and sheds magnetism quickly and steel doesn't. the trouble is that all too many vendors don't know the difference, particularly those handling wrought iron who are often selling steel as iron. (In a few years there will be a lot of complaints since, as we know, iron doesn't rust whereas steel does). I don't know where to get true iron fine wire. ------------------------ Daniel McFarland Cook discussion board // related to replication roundhousechalkfarm.jpg (853 kB, 942x782 - viewed 678 times.)

I going to follow up on your gas spectrometer suggestion for analysis of a few cheap domestic wire sources here [IE.. floral twist wire . see if Steve can use the University Lab for this testing ?. had a few crazy days here ,but seems I can make some more calls tomorrow to other Vendors for Mil specs and pricing .

Group: Professor Hero Member Posts: 1940	Much early work with Fe used "Swedish Iron" or "Norway Iron" because iron ore from that area had particularly good magnetic characteristics. You will find some data on these and many other irons in "International Critical Tables of Numeric Data" first published in 1929 by The National Research Council of the USA. A Google search will find archive copies in pdf format, I have one on my computer, file size 23MB. I can post it here if necessary. Below are two extracts.
