They are an upgraded type of spark plugs that use ruthenium metal to make the electrodes. They are a recent development of spark plugs manufactured from a rare, hard metal that can endure high temperatures. Spark plugs are crucial for your car because you cannot power or move your vehicle anywhere without them. Spark plugs also thrive in very high temperatures and pressure, so they help burn off any contaminants and deposits caused by fuel additives. So, the spark plugs make your car power up and keep it in motion by burning the compressed air and fuel smoothly. It helps ignite the compressed air or fuel mixture and still contain the pressure of combustion in the engine and therefore start your car. What are Spark Plugs?Ī spark plug is equipment used to send electric currents to the combustion chamber from the ignition system. All in all, these two plugs brand are reliable, and offer better performance than most competitive brands. The main different is that iridium plugs are expensive, however, ruthenium plugs seem to be last longer, but iridium has a higher melting point compared to ruthenium. However, since ruthenium and iridium are the best plugs and best options, most car owners find it challenging to choose.Īre you wondering what spark plug to pick between ruthenium and iridium?īut what is the main difference between ruthenium vs Iridium? Spark plugs do not change more often the first modification is from copper to platinum spark plugs, and now there are ruthenium & iridium spark plugs as the recent changes.īoth i ridium and ruthenium spark plugs make the engine perform better and increase the internal engine combustion life span.Įvery automobile engine requires a change of spark plugs over time. They enable the engine to operate by igniting the fuel, ensure fuel efficiency and improve the engine’s performance. Spark plugs are part of the crucial elements of your car’s engine. If you want a more “classic” platinum that’s easy to work with and builds character over the years, choose a platinum-iridium alloy.Here’s my honest Ruthenium Iridium comparison. If you want to create platinum pieces that last longer and cost less, choose a platinum-ruthenium alloy. Ruthenium also trades at a much lower price per ounce than iridium, so ruthenium-based alloys cost less. This makes it a great alloy not just for jewelry, but also industrial-grade parts. If you can mold platinum-ruthenium without cracking it, it lasts for a very long time. It’s resistant to wear and tear, but because its hardness is so much higher than platinum-iridium, it’s difficult to mold and takes greater skill to work with to avoid cracking it under excessive pressure. So while it’s great for hand fabrication and small pieces of jewelry, it doesn’t hold up well over time.ĩ50 Platinum-ruthenium alloy is the opposite.
This makes it easy to work with, but it’s vulnerable to dents, scratches, and deformation. Generally, 950 platinum-iridium alloy is soft and malleable. The most common casting grain we sell is 95% platinum alloyed with 5% ruthenium.
This alloy has become less popular in recent years.
Historically, platinum was always alloyed with iridium generally using a mixture of 90% platinum and 10% iridium. Here, we’ll discuss the differences between the two alloys. Both iridium and ruthenium belong to the platinum family of metals, but they confer different benefits when alloyed with pure platinum. Lately, we’ve heard a few jewelers in our shop express confusion over whether they should order platinum alloyed with iridium, or ruthenium.
