Iridium mixes well with Platinum therefore, the finished product should have minor porosity and yield a beautiful luster after the final polish. If the mix was 95% Platinum / 5% Iridium, it would be too soft for jewelry. To use Iridium, the mix needs to be 90% Platinum / 10% Iridium, which makes the final Platinum metal hard enough to work with. Iridium is also a softer type of metal but harder than Platinum. _ Iridiumįirst of all, pure Platinum is by nature soft and “chewy,” so it cannot be used for jewelry in this form and therefore needs an alloy to strengthen it. There are two major Platinum alloys used in fine jewelry, one is Iridium and the other is Ruthenium. In this article series, I will explain why that depends on the different alloys used and manufacturing techniques, what are the differences between the two metals, the impact each has on price, the impact on longevity, which is best for what kind of jewel and ultimately the decision that is best for you.
RUTHENIUM VS IRIDIUM SERIES
So, what's your take ? Can you educate me on spark plugs ? On most 4 cylinder they are real easy to replace so I always them as a maintenance item, replace every few years and don't think twice about it.Īll of the NGK Laser series have a platinum wear disc on the ground electrode. If the Laser iridium have indeed only one iridium (or platinium + iridium) pointy electrode, I can see the Ruthenium lasting longer. There is little I can find about Ruthenium spark plugs, except it's the new sliced bread, better, last longer, etc etc. Ruthenium seem to have two visible pointy electrodes of whatever fancy metal they are advertised. Not sure about the replacement interval, but it's a very long thing like 100k Km. I always thought the Laser iridium meant double iridium electrodes, but now that I look closely I can only see one ? Price is identical, actually the Ruthenium are a few cents cheaper, but that's negligible. On the right, standard iridium that are OE on the car. So, spark plug replacement time for the Mazda (2.3 engine). This should make changing the spark plugs in our 3 Ford OHC engines a snap. I bought a one piece 10" long swivel magnetic spark plug socket from Auto Zone for ~$13. By then we should have around 46-47,000 miles on the factory plugs.
I'll definitely change them by late summer if there is no problem sooner. We have just over 40,000 miles on the Explorer now and it runs great and the engine is smooth, but typical Ecoboost noisy outside of the vehicle and quiet inside. I bought a set from Rock Auto when getting other stuff, I think the Motorcraft plugs costed about $4.50 each, a bargain. I think your 1.6 EB uses the same plug as our 2.3 EB, the Motorcraft SP-537 (CYFS-12Y-2), iridium. WHY I want to replace my factory Motorcrafts in a 1.6 EB with only ~20K miles on them.Įasy enough to do on this platform, so worth 'the bother'. What vehicle did they come out of? Was it a Turbo DI engine? Time will tell.įor only 70,000 km or about 44,000 miles they seem well worn for iridium plugs. As someone else has said, they look fragile. Only about 70K km on them, but I'm glad I did - lots of wear on the ground electrode on the old plugs, to the point where the gap was about 50% larger than spec.
