These all metal heat breaks are the cheapest option on the market. They are relatively cheap to make and their thermal conductivity is relatively high - about 45 W/m-K (Titanium - 6.7 W/m-K). I would not recommend this type of heat break for any high-end or mid-range 3D printer. These heat breaks are a very cheap option for low-end 3D printers.
This is how a cross-section of a V6 hot end with a stainless steel heat break looks like (without the heatsink).
It is the heaviest heat break in comparison to copper, titaninum, copper + aerospace heat breaks.
As you can see in the comparison below, the weight is:
Standard all metal heat break: 3.32 g
Titanium heat break: 1.85 g
The lightest V6 standard size heater block on the market. This particular type is top quality as you can see in the pictures below and it is CNC machined from an aluminium block. It conducts heat from heater to nozzle…
What nozzle does my printer use? This is a very common question.80% of hobby 3D printers use a V6 nozzle.If you can see your hot end setup in the pictures below, this is the right article for you. Where can…

This is my most favourite heat break for PLA. Bowden tubes goes all the way through the heat break and touches the nozzle. I would recommend this heat break for printers using only PLA without carbon/sparkes/wood and nothing else, because…
This is the newest and most hi-tech heat break from Mellow. It combines one of the best affordable materials – copper for it’s high thermal conductivity and aerospace grade ceramics for thermal insulation between the heat block and heatsink. Order…
