If light weight and affordability is your main concern, titanium is a good choice. Otherwise, go with palladium.
Platinum has a heavier feel, making it feel more substantial. Titanium, while extremely strong, is lightweight and ideal for those who do not like heavy jewelry. Besides their inherent strength as a metal, both platinum and titanium are hypoallergenic, making them great options for people with sensitive skin.
Rarity : One of the largest differences between titanium and platinum is how rare, or not, each metal is. While titanium is one of the most abundant metals found on the earth's surface, platinum is quite rare. This rarity makes platinum extremely valuable.
Of the two metals, platinum is stronger than palladium, but again both metals are strong enough to be used for engagement rings or wedding rings that are worn daily.
Like most other precious metals Palladium does scratch. Despite being harder than Platinum, it will nevertheless pick up scratches.
Some people don't like the 'light' feel of palladium compared with platinum. Because it's a newcomer to the jewellery market, it's too soon to say whether palladium will keep its value so it's probably not the best metal to choose if you're looking to make a long-term investment.
Still, if you find a retailer with the style you want, it's one of the better platinum alternatives. Buy palladium rings if you have sensitive skin and need a hypoallergenic metal. Additionally, choose palladium if you don't like heavy rings and want a cost-effective option for your wedding band or engagement ring.
Palladium-catalysed reactions are so valuable that, in 2010, their discoverers shared a Nobel prize. But despite its versatility, chemists are trying to move away from palladium. The metal is more expensive than gold, and molecules that contain palladium can also be extremely toxic to humans and wildlife.
Palladium is the most expensive of the four major precious metals – gold, silver and platinum being the others.
Overview of costliest precious metals
Iridium is another PGM with a silver/white appearance. It is the second most dense material next to osmium and extremely rare ─ more iridium is found in meteorites than in the earth's crust.

Because it's a natural metal that's abundant, and also because it's relatively easy to manufacture compared to other metals, titanium is much cheaper than gold, platinum, and similar precious metals.
As mentioned above, tungsten is the strongest of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it's a brittle metal known to shatter on impact. On the other hand, Titanium has a tensile strength of 63,000 psi.
Pure titanium does not rust or tarnish like iron metals, allowing for prolonged exposure to water without the worry. In addition, titanium is even fully resistant against the corrosion effects of saltwater. This resistance is from a thin oxide film that covers the surface of pure titanium when exposed to oxygen.
Palladium vs Platinum: Permanence
Both palladium and platinum are durable metals and hold up better to wear and tear than gold. However, palladium is slightly more scratch-resistant than platinum, making it a great option for people whose jewelry might face a little more wear-and-tear.
Palladium is more rare than platinum and is used more widely in industrial applications.
Corrosion resistant: Palladium is about as resistant to corrosion as gold, with a natural resistance against oxidation.
Palladium's most incredible ability is that it can absorb up to 900 times its volume of hydrogen, according to the Thomas Jefferson National Accelerator Facility. Because of this ability, palladium is used to store and filter hydrogen.
In fact, palladium is currently the most expensive among the four major precious metals (platinum, gold, and silver).
So, is it a good time to buy palladium? We believe so. The market factors indicate that 2022 would be a great time for precious metal investors to get in on the palladium market. If you are new to coin and precious metal investments, you don't have to worry about entering the market blindly.
Palladium is used in emission-reducing catalytic converters in gasoline engines, but the metal's price surge has driven automakers to replace it with platinum.
Iron-aluminium compound could replace palladium catalyst, reducing the cost of plastic production. (Phys.org) -- Chemists don't like precious metals – at least not when they need the expensive materials as catalysts to accelerate reactions or guide them in a particular direction.
Though palladium is considered the most reactive in the platinum metal group, it doesn't react with water. You can wear it in the shower, and it won't tarnish. Over time, the glossy finish might fade to a matte one. But you can get it polished by a jeweler to restore the original look.
Palladium will not tarnish and is great for filigree work, allowing for a broad spectrum of designs.
Palladium prices have dropped by a third since soaring to all-time highs six months ago, as automakers switch to platinum and other metals that do a similar job of limiting the toxic emissions of petroleum engines, a trend that is seen continuing in 2022.
